I need some help I posted the first question to this a bit ago but didn't enter it correctly so sorry to those who helped! I also have a 2nd half which I understood till they added the dividing part.

I need to find the first five terms of each recursive sequence.

1.C1=64, C2=32

Cn= Cn-2 - Cn-1/2

Next!! Find the indicated partial sum for each sequence.

2. An=1/n; S5

3. An= n/n+1;S4
