Basic Term in General for Arithmetic Sequence:

A[n], general n term
A[1], first term
n, index of the term
d, common difference to each successive term

Let a be the first term of the sequence, d understood as already said;

Subtract corresponding equation members:

You also want to know "a". Use either equation from the system.

You can find the first few terms of the sequence......!
