In A.P. , the formula is ---------
b-a = c-b
=> 2b = a+c


Let,
a = 2k
b = (4k-3)
c = (4k+4)

(4k-3) - 2k = (4k+4) - (4k-3)

=> 2(4k-3) = 2k + (4k+4)

Now calculate the value of "k"



Hope it will help you .

a=2k
d=2k-3
n=3

Tn=a+(n-1)d
T3=2k+(3-1)(2k-3)
4k+4=2k+2*2k-3
4k+4=2k+4k-6
4k+4=6k-6
4k-6k=-6-4
-2k=-10
2k=10
k=5

Explode: No it's wrong Sister
