Final answer:

The formula for the partial sum of an arithmetic sequence provides a way to find the sum of the first n terms. To find the value of a specific term in the sequence (an), we can rearrange the formula.

Step-by-step explanation:

The formula for the partial sum of an arithmetic sequence is:

Sn = n/2(a1 + an)

To solve this formula for an, we can rearrange it as follows:

an = 2(Sn/n) - a1

where Sn is the sum of the first n terms, a1 is the first term of the sequence, and an is the nth term of the sequence.
