If a sigma notation starts at n=0 and ends at 22, how many terms do we have?

And how many terms do we have when it starts at n=1 and ends at 22?

Do we use the (last term - first term +1) rule for both?

If a sigma notation starts at n=0 and ends at 22, then we will have 23 terms.

If a sigma notation starts at n=1 and ends at 22, then we will have 22 terms.

Yes, we use the (last term - first term +1) rule for both.
