sigma (3+n)/(2+2n) n=1 to infinity
a) Σ^6 k+1/2k
b) Σ^6 k+2/2k
c) Σ^6 k+2/2^k
d) Σ^7 (1+(k+1)/(k+2))
a,b,and c the symbol of sigma sign has k=2 on the top but the last one has k=4. These options or answers are different. I have to choose one of them

I agree with bob's expression.
If there are only 5 terms, and they are:
1+ 5/6+ 6/8+ 7/10 + 8/12
= 4/4 + 5/6 + 6/8 + 7/10 + 8/12
= Σ (n+3)/(2n+2) from n = 1 to 5
In the standard notation of sigma , the index usually starts at 1.
The choices you give are not standard answers.
