Question

If a-2d,a-d ,a,a+d,a+2d are in AP then the common difference is

Answer 1

The common difference is 'd'

Step-by-step explanation:

Common difference in AP : is the constant difference between the consecutive terms,

i.e. if a, b, c, d....... is and A.P.

Common difference = b - a = c - b = d - c = ......

Here,

a-2d,a-d ,a,a+d,a+2d are in AP,

Thus,

Common difference = (a-d) - (a-2d) = a - d - a + 2d = d

Verification :

a - (a - d) = (a+d)-a = (a+2d)-(a+d) = d.
