# Find the nth term 1 + 4 + 7 + 10 + 13 ⋯

We will use the concept of sequence and series in order to find the nth term.

## Answer: nth-term a_{n} = 1 + 3n

Let us see how we will use the concept of sequence and series in order to find the nth term.

**Explanation**:

This is an arithmetic sequence.

First-term a_{1} = 1

Second-term a_{2} = 4

Thied-term a_{3} = 7

Forth term a_{4} = 10
