6^3=216/5=43.2
5^3=125/4=31.25
4^3=64/4=21.33
So 3^3=27/2=13.5

6, 5, 43.20
(6)^2 - (5)^2 = 11 and 43.20 - 11 = 32.20 and 32.20 - 31.25 = 0.95
(5)^2 - (4)^2 = 9 and 31.25 - 9 = 22.25 and 22.25 - 21.33 = 0.92
(4)^2 - (3)^2 = 7 and 21.33 - 7 = 14.33 and 14.33 - 0.89 = 13.44

Since the difference is 0.95, 0.92....0.89

Hence 13.44 is the answer according to series

Nupur  (9 years ago)

Let the pattern be : a , b , c
c = a * (a+1) + a/b

43.2 : 6*7 + 6/5
31.25 = 5*6 + 5/4
21.33 = 4*5 + 4/3

Ans is 13.5 ( 3*4 + 3/2)

Is this solution Helpfull? Yes (4) | No
