We know that,
a2-a1=a3-a2
So,
4k-6-(k+2)=3k-2-(4k-6)
4k-6-k-2=3k-2-4k+6
3k-8=4-k
4k=12
k=3

K = 3
step-by-step explanation:
Let the given terms be,
a = k +2
b = 4k -6
c = 3k -2
Now,
we know that,
if three consecutive terms a, b and c are in A.P,
then,
a + c = 2a
=> k+2 + 3k - 2 = 2( 4k -6)
on simplifying,
we get,
=> 4k = 8k - 12
=> 8k - 4k = 12
=> 4k = 12
=> k = 12/4
=> k = 3
Hence,
the value of k so that the terms are kn A.P is 3.
