Question

if K, 2 k - 1 and 2 k + 1 8 3 consecutive term of an ap then the value of k is
​

Answer 1

Here the terms are given in an A•P

THEREFORE,

K, 2K-1, 2K-18,......

Now as it is already given in A•P;

which implies that the difference b/w each term would be same.

=> 2K-1-(K) = 2K+18 - (2K-1)

=> 2K-1-K = 2K+18 -2K+1

=> K-1 = 19

=> K= 19+1

=> K= 20

YOU CAN CHECK BY PUTTING THE VALUE OF k IN THE GIVEN QUESTION.
