Question
The following numbers form a series followed by a (?).
Find the odd one out first and then find that what will come in place of the question mark (?) according to the corrected series? 14, 51, 222, 1125, 6786, ?Solution
(5 + 2) × 2 = 14 (14 + 3) × 3 = 51 (51 + 4) × 4 = 220 (220 + 5) × 5 = 1125 (1125 + 6) × 6 = 6786 So, 220 should come in place of 222 And, the number that will come in place of (?) = (6786 + 7) × 7 = 47551
