Question

Which of the following are APs? If they form an AP, find the common difference d and write three more terms. 2, 4, 8, 16.

Philoid · Accepted Answer

For a series to be in AP, the common difference (d) should be

Equal.

D₁ = second term – first term = 4 – 2 = 2

D₂ = Third term - Second term = 8 – 4 = 4

Since common difference is not equal the above series is not in AP

Which of the following are APs? If they form an AP, find the common difference d and write three more terms.2, 4, 8, 16.
