Question

From an A.P. 5 consecutive terms are required to be written. The central term out of the five terms is given as 5 and it’s informed that the common difference of the A.P. is 4. Write the 5 terms in the correct sequence.

• A. 1,3,5,7,9
• B. 3,4,5,6,7
• C. -10,-5,5,10,15
• D. -3,1,5,9,13

Answer 1

The correct option is D

-3,1,5,9,13

Since the A.P. has a common difference of 4, so the term before the given term can be obtained by subtracting 4 from it and the term after the given term can be obtained by adding 4 to it.

Hence the terms in the correct sequence are -3,1,5,9,13
