Thread: series

I think i found the bottom one, 2n+3 the only way i can see the top one is in a recursive but i need a closed form, can anyone give me some hints on how to look at it...


Find a formula for sn, n 1. , , , , , , ...

numerator looks to be

yes, the general term is n! / (2n+3);

The numerator is .

So

.


If this was an infinite series, it would diverge btw. But since it's finite, that's a bit trickier...
