Anyone... please help answer this

What's the next number in this sequence

1, 2, 8, 176, 260480, ___

[donf]

I think the next number would be 8,340,992. Do not take this answer as Gospel!

Donf - how did you arrive at this? I'm stumped...

[Unknown008]

Seem to me an exponential sequence... so your answer donf is possible... though I don't know what the power factor is. But there must be something before the powering up, as one to the power of anything is always one. Ok, trying to look for it...

[Unknown008]

Oh, no! Excel cannot do it. I can't find an equation to fit in... I'm stumped too.

[ebaines]

I think I've solved it. The next number in the sequence is a huge one:

11,949,684,623,360

The sequence goes like this: given A and B are two consecutive members in the sequence, the next number is AB(A+B+1).

[donf]

The power factors are multiples of 4.

1+2 (x4) 8 (8+3=[11x16=] 176) 176+260480 X 256 = 66,727,936

[ebaines]

The power factors are multiples of 4.

1+2 (x4) 8 (8+3=[11x16=] 176) 176+260480 X 256 = 66,727,936

Donf - I don't see where the 3 came from for (8+3)x16 =176? Also, how does your solution generate 260480?

[donf]

The number line is 1 2 8 176 260480 (?)

1+2+8 = 11

[ebaines]

So how does your solution generate 260480? It seems your method would give a different value, namely (1+2+8+176)*64 = 11968

[Unknown008]

And if it's the square of four, I have (1+3+8+176)((4^2)^2) I have 47872!

to find the expodenial value of a sequence you
find out how many times it takes until the
differences equal each other
for ex.
1 8 27 64 125
7 19 37 61
12 18 24
6 6 3 deductions=3rd exponet
so,
1 2 8 176 360480
1 7 168 360304
6 161 360136
155 359975
for the most part, it has no exponets
that should help.
