Question

What is the common difference of the arithmetic sequence 5, 8, 11, 14?

-3

8/5

3

9

Answer 1

The common difference is 3

Explanation:

we know that

In an Arithmetic Sequence the difference between one term and the next is a constant called the common difference

we have

`5,8,11,14`

so

`a1=5`

`a2=8`

`a3=11`

`a4=14`

`a2-a1=8-5=3`

`a3-a2=11-8=3`

`a4-a3=14-11=3`

therefore

The common difference is 3
