Question

The value of d (common difference) of an A.P. such that the three consecutive terms of an A.P. are the consecutive terms of the G.P. (a is the first term of the A.P)

• A. d = a
• B. d = 0
• C. d =2a
• D. a = 4a

Answer 1

The correct option is B

d = 0

Let the three consecutive terms of A.P. be a, a+d, a+2d

$\left(a\right)(a+2d)=(a+d{)}^2$

$d=0$
