Four number groups are given, out of which three are same in a certain way. Find the odd group that does not belong to the group?

(4, 16, 48)

(4, 16, 48)  =  4²  →  16  →  × 3   →  48

(4, 36, 90)  =  6²  →  36  →   ×\(\frac{5}{2}\)   →  90

(8, 64, 160)  =  8²  →  64  →   ×\(\frac{5}{2}\)   →  160

 (10, 100, 250)  =  10²  →  100  →   ×\(\frac{5}{2}\)   →  250
