The sequence starts at 12 and the rule is to **add 2 **to the previous term.

The 1st term is 12.

The 2nd term is 14.

The 3rd term is 16.

The 4th term is 18.

The 5th term is 20.

**Example**

A sequence starts at **15** and follows the rule to **add 3 **to the previous term.

What is the **5th** **term** of this sequence?

**Answer**

The 1st term is 15.

The 2nd term is 15 + 3 = 18.

The 3rd term is 18 + 3 = 21.

The 4th term is 21 + 3 = 24.

The **5th term **is 24 + 3 = **27.**
