answer is 32
(5x4)+4(4-1)=20+12=32 which is answer all other equations are such arrangement
Find the number that comes next in the following series:
3, 7, 12, 14, 16, 19, 21, 25, 30, 41, 45, 52, 54, 56, 59, 61, 65, 70, ?
If 51 x 51 = 26 01 52 x 52 = 27 04 53 x 53 = 28 09 54 x 54 = 29 16 55 x 55 = 30 25 56 x 56 = 31 36 then 57 x 57 = ?? ??
If 16+24 = 12, 36+54 = 27, 20+60 = 25 then 28+72 = ?
