Question

Does the sequence of odd numbers form an AP?

• A. Yes, with a common difference of 1.
• B. No
• C. Yes, with a common difference of 2.
• D. Yes, with a common difference of -1.

Answer 1

The correct option is C

Yes, with a common difference of 2.

Odd numbers are 1,3,5,7,…

First term = 1.

Second term = 3

difference = 3- 1 = 2

Similarly, 5-3 = 7-5 = 2

Observe that the difference between any two consecutive terms is 2 .
Hence it forms an AP.
