Question

find the value of k

Answer 1

Answer:

2.4

Step-by-step explanation:

Since the no.s are in AP,

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

  6-2k-1 = 3k+1-6

     5-2k = 3k-5

        5+5 = 2k+3k

           10 = 5k

$\frac{10}{5}$ = k

   k = 2

Answer 2

Answer:

d=6-(2k+1)

d=(3k+1)-6

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

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

5-2k=3k-5

-2k-3k=-5-5

-5k=-10

k=2
