Question

In which of the arithmetic sequences given below, 37 is a term ?

• A. 4, 9, 14, ....
• B. 7, 12, 17, ....
• C. 8, 12, 16, ....
• D. 7, 11, 15, ....

Hint:

To quickly check if a number is a term in an AP, subtract the first term from the number (aₙ - a) and see if the result is divisible by the common difference d. In option (B), 37 - 7 = 30, and 30 is divisible by the common difference 5. This is a fast way to verify the answer.
