Find the explicit formula c1=1, c2=2, cn+1 = (cn + cn-1)/2 ; n>2

2. Relevant equations

3. The attempt at a solution

c1 = 1

c2 = 2

c3 = 3/2

c4 = 7/4

c5 = 13/8

c6 = 27/16

c7 = 53/32

c8 = 107/64

I know the bottom term is 2^n-2. I cannot find what the top is. If anyone sees it let me know thx.

Also if you know general form of 1, 1, -1, -1, 1, 1, -1, -1 ....
