Given three terms are in A.P so,2(2k-1)=k+2k+1;4k-2=3k+1;4k-3k=1+2;k=3
Therefore k=3
it is 4k -2 = 2k+1.... you wrote 4k - 4..

if three terms are in AP, then sum of the first and third are twice the middle.
k + 2 k +1 = 2 (2k -1)
k = 3
so 3, 5, 7 are in AP
k + 2 k +1 = 2 (2k -1)
k = 3
so 3, 5, 7 are in AP
I got k=5
its absolutely correct
