Question

Look at the pattern below.
52, 104, 208, 416, ...

Which number sentence can be used to determine n, the 8th number in the pattern?

Answer 1

divide it all by 52, what do we get?

Answer 2

ummm?
a n = 26 ÷ 8
b n = 26 × 82
c n = 26 × 28
d n = (26 × 8) - 4
i got B as my answer

Answer 3

52(1,2,4,8,...)

a_n+1 = 52 * 2an

an = 52 * 2^n is what it looks like to me

Answer 4

if n starts at 0 :)

so n=7 is the 8th term
