# A math challenge

I would like some help from some of you who are good at math.

I would like to know the steps following:

1: 8
2: 16
3: 70

Between step 1 and 2 there is a 100% increase. Between 2 and 3 there is a 437,5 % increase. What is step 4 and 5 following the same exponential trend?

I am not sure how to calculate the next steps, so help is appreciated.

Edit: not sure if this is correct forum, but seemed the best place.

Did you try something easy like feeding excel your numbers and letting it calculate a best-fit-curve?

Anyway, I did:

Best fit (exponential): y = 2.3737 e^1.0845 (fitting index 0.9584)
Best fit (linear): y = 31x -30.667 (fitting index 0.845)
Best fit (logarithmic, *not very good for this data*): y = 51.601 ln(x) + 0.5147 (fitting index 0.7225)
Best fit (polynomic): y = 23x^2 -61x+46 (fitting index 1, as expected by only 3 datapoints and a formula with x^2)
Best fit (potency): y = 6.8004x^1.8694 (fitting index 0.8789)

Okay, the very best is obviously the fourth formular (polynomic), which would give you y(4) = 170, y(5) = 316.
If this has to be an exponential formular, it would give you y(4) = 181.7169 and y(5) = 537.5114.

Dude I don't wanna state the obvious, but
1.could it be a birth date, or
2. Are there more numbers missing from this equation ?

Didn't know you could use excell for that.

So the steps would be:
8
16
70
181,7
537,5 ?

1st step 8-16 is 100%
2nd step is 16-70 is 437,5%
3rd step is 70-181,7 is 259,57%
4th step is 181,7-537,5 is 295,8 %

The 3rd and 4th step should see a larger %-wise increase shouldn't it? I thought both would have increasingly higher % increase than 437,5.

You might have falsely inferred that the next number in succession is a simply calculation
of proportion. Could this be an IQ type question where every possible answer from every possibly
angle must be calculated?

When I said "math challenge" it wasn't in the form of a mystery, more in the line of: "I don't know how to calculate this!"

I figured that but I was just checking...

sorry...I loathe calculation

Is it printed just as you have it here, with colons?

1: 8
2: 16
3: 70

or
1. 8
2. 16
3. 70

okay same exponential trend huh?

So 70 would be 140
140 would be 612.5

The colons or periods are incidental. Could write it as: 8, 16, 70 or

8
16
70

I just did a google search for 8:16:70 and a lot of the responses I got were mainly dates, BUT there were also quite a few hits for LINEAR ALGEBRA equations.

I don't know what linear algebra is, but I hope this can help you on your quest.

I love number sequences...so I had to register just to solve it for you

8, 16, 70, 496, 3852

8^x + 8 - (x^x - x)

x=0
8^0 + 8 - (0^0 - 0)
1 + 8 - (1 - 0)
1 + 8 - 1 = 8

x=1
8^1 + 8 - (1^1 - 1)
8 + 8 - (1 - 1)
8 + 8 - 0 = 16

x=2
8^2 + 8 - (2^2 - 2)
64 + 8 - (4 - 2)
64 + 8 - 2 = 70

x=3
8^3 + 8 - (3^3 - 3)
512 + 8 - (27 - 3)
512 + 8 - 24 = 496

x=4
8^4 + 8 - (4^4 - 4)
4096 + 8 - (256 - 4)
4096 + 8 - 252 = 3852

Awesoem job, how did you come around to that formula? trial and error?

i was crunching some numbers.. i even went into the exponential growth formula lol.. i ave up after 20 mins.

Folks, this is ATS, these are not numbers in a sequence, these are codes in the bible that indicate Col. Mustard did it with the knife, in the study.

well done firemonkey and welcome to ATS.

Yes, just seeing a start of a pattern involving 8 and realizing that 64 (8^2) was close to 70. I knew I had to get to add 6 to get to 70, but adding 8 and subtracting 2 works just as well...so I realized the first two terms were deceptively simple. Just kind of worked backwards from there.

It is probably not the only solution, but it is one solution.

Damn! I came up with Miss Scarlett in the Library with the candlestick.However,if you transpose the numeric sequence with the appropriate Nostradamus quatrains it reveals:"The world as we know it will end sometime after 2013"

1 + 8 - 1 = 8

8 + 8 - 0 = 16

4096 + 8 - 252 = 3852

8
16
70
496
3852

8-16 100%
16-70 437,5%
70-496 708,5%
496-3852 776,6%

This is definitely closer to what I was expecting, at least the step from 70 to 496. But somehow the next step seems to small. Again; I have yet to acquire the math skills myself, so I appreciate all of your efforts. And maybe the number IS accurate, time will tell in any case.

And I had to chuckle a bit, with the ideas presented to what the numbers signify, but I guess I should have anticipated this, considering this is ATS

Please send me a new laptop. I just spewed tea all over it.
