Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
= first term of an arithmetic sequence
= common difference
The second term is

The third term is
and can also be calculated as
because
The fourth term is
and can also be calculated as
It goers on like that adding one more every time, so
the nth term is

Hopefully you see how the formula makes sense, and how we got to that formula.
If you do, you do not need to memorize the formula because you will know that to get to the nth term
you added again and again for a total of times.
You would never need to ask for that formula either.
