Question

if 2K + 1, 6, 3 k + 1 are in AP find k​

Answer 1

Answer:k=12

Step-by-step explanation:

A2-a1=a3-a2

6-2k-1= 3k-1-6

5-2k=-7+3k

K=12

Answer 2

Answer:

k=2

Step-by-step explanation:

a2-a1 = a3-a2 (Because they are in AP)

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

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

5-2k = 3k-5

5+5=3k+2k

10= 5k

k= 10/5

k=2
