Question

k Consecutive rank for which of 2K+1,6K+3,5K-1 for A.P

Answer 1

Answer:

The value of k is -6/5

Step-by-step explanation:

Given ::- AP - 2k + 1 , 6k + 3 , 5k -1

To find ::- value of k

Solution ::-

Common difference = 6k + 3 -(2k+ 1)

Common difference = 5k -1 - (6k + 3)

We know that, the common difference is same in an AP

So,

6k + 3 -(2k + 1) = 5k -1 - (6k + 3)

6k + 3 -2k -1 = 5k -1 -6k -3

4k + 2 = -k -4

4k + k = -4 -2

5k = -6

k = -6/5

Therefore the value of k is -6/5
