How to Find the Partial Sum of an Arithmetic Sequence

If we know the formula for the partial sums of a sequence, we can find a formula for the nth term in the sequence. The partial sum of a sequence gives as the sum of the first n terms in the sequence. If you're seeing this message, it means we're having trouble loading external

Partial Sums

This is the Partial Sum of the first 4 terms of that sequence: 2+4+6+8 = 20. A Sequence is a set of things (usually numbers) that are in order. A Partial Sum is the sum of part of the sequence.
