We're doing sequence things in class how do I find the general term of this set (4,8,6,16,8,32,10,64). The answer must be in an equation.

Question

The next in the sequence would be 12, 128. I thought the answer was f(x) = 2x but that doesn't account for 6,8,10

Answer 1

Looks to me like
Tn = 2n+2 if n is odd
Tn = 4*2^(n/2) if n is even

Answer 2

Hmmm. Better make that

Tn = n+3 if n is odd
