Question

How do I find the common difference of the arithmetic sequence 2, 5, 8, 11,...?

Answer 1

`color(blue)(d=3`

Explanation:

The arithmetic sequence provided is :
`2,5,8,11`

There is a common difference maintained between any two consecutive numbers of an arithmetic sequence.

`d = 5-2 =3`
`d=8-5 = 3`
`d= 11-8 =3`

So the common difference of this arithmetic progression is
`color(blue)(d=3`
