step-1 27+3=30/2=15.
step-2 56+6=62/2=31.
step-3 9+81=90/2=45

step 1 : 1*3=3,5*3=15,9*3=27
step 2 : 1*6+0=6,5*6+1=31,9*6+2=56
step 3 : 1*9=9,5*9=45,9*9=81

3+12 = 15+12 = 27 -- -3,15,27.
6+25 =31+25 = 56 --- 6,31,56.
9+36 = 45+36 = 81 --- 9,45,81.

Logic is mid = (up+end)/2.
(3+27)/2 = 15.
(6+56)/2 = 31.

So (9+81)/2 = 45.

(27+3) = 15.
(6+56) = 31.
Then (81+9) = ?

(27+3)/2 = 15.
(56+6)/2 = 31.
(81+9)/2 = 45.

(15*2) -3=27.
(31*2) -6=56 //gap between these numbers (15 to 31) is 16.
(45*2) -9=81 //gap between these numbers (31 to 14) is 14.
