Question
Which of the following lists of numbers form an A.P.? If they form an A.P., find the common difference d and write the next three terms : 4, 10, 16, 22,…
Solution
4, 10, 16, 22,…
Here a = 4, d = 10 – 4 = 6, 16 – 10 = 6, 22 – 16 = 6
∵ common difference is same
∵ It is in A.P
and next three terms are 28, 34, 40.
