Question

for what value of k will 2k+1,6k-1,5k+7 the first three term of anA.P.​

Answer 1

Answer:

Hello friend!

As we all know , the difference between consecutive terms of AP is same.

So that means-

(6k-1)-(2k+1)=(5k+7)-(6k-1)

6k-1-2k-1 = 5k+7-6k+1

4k-2 = 8-k

4k+k=8+2

5k=10

k=2

Now that we have got the value of k , we can easily find out the terms.

2(2) + 1 = 5

6(2) - 1 = 11

5(2) + 7 = 17

Thus the terms are 5 , 11 and 17.
