Question

Which is an arithmetic sequence?

A) 9, 12, 16, 20...

B) 9, 11, 13, 16...

C) 1, 5, 9, 13, 17....

D) 1/2, 1/4, 1/6, 1/8....

Answer 1

`C ) 1,5,9,13,17...`is the Arithmetic sequence.

Explanation:

`C ) 1,5,9,13,17...`is the Arithmetic sequence.

Here ,

1st term = a = 1 and common difference = d

`d=17-13=13-9=9-5=5-1=4`

Hence,

c) 1,5,9,13,17...is the Arithmetic sequence.
