Index n_______________Term
1_____________________2
2_____________________2+3=5
3_____________________2+3+5=10
4_____________________A[3]+7=17, 2+3+5+7
5_____________________A[4]+9=26, 2+3+5+7+9
6_____________________A[5]+11=37, 2+3+5+7+9+11
3+2(i-2) which requires i>1.
Each term is a summation but needs to have the summation happen for n>1.
2+ sum of as i goes from 2 to n.
