Question

if 8k +4, 6k-2 ,2k+12 are in a.p. then the value of K is​

Answer 1

Answer:

when these r in ap then,

8k+4 + 2k+12 = 2(6k -2)

= 10k +16 = 12k -4

= 16+4 = 12k-10k

= 20 = 2k

= k = 10

Answer 2

Answer:

K=3

Step-by-step explanation:

1. Given that a1=8k+4 and a2=6k-2

FINDING

1. d=a2-a1
2. d=6k-2-(8k+4)
3. d=6k-2-8k-4
4. d=-2k-6
5. -2k=-6
6. k=6/2
7. k=3
