Which of the following is an arithmetic sequence?

A. 1, 2, 4, 8, 16, 32, ...

B. 100, 50, 25, 12.5, ...

C. 1,3,5,7,9,11, ...

D. 1,2,4,7, 11, ...

C. 1,3,5,7,9,11 ...

Step-by-step explanation:

difference = 3 - 1 = 2

Each term is obtained by adding 2 to the previous term

In Arithmetic Sequence, (n + 1) th term = nth term + d

The one adding the same number to get to the next number in the sequence.

Step-by-step explanation:

An arithmetic sequence is a sequence that adds (or subtracts) the same constant every time.

A multiplies by 2 each time.

B divides by 2 each time.

C Adds 2 each time.

D Adds an increasing number each time.
