Given Option (B),(C), (D)
are same and follow that pattern
(B) 21: 462 that is follow the pattern 21 × 21 = 441 + 21 = 462
(C) 14: 210 it is follow the same pattern 14 × 14 = 196 + 14 = 210
(D) 25:650 it is follow the also the above pattern 25 × 25 = 625 + 25 = 650
but Option (A) 7:50 it is not follow that pattern 7² = 49 + 1 = 50
therefore Option (A) 7:50 is different pattern follow of the given option hence it is Odd .
so (A)7:50
