Correct Answer - Option 4 : 125

The pattern of the original number series is

⇒ 18

⇒ 18 + (22 + 2) = 24

⇒ 24 + (32 - 2) = 31

⇒ 31 + (42 + 2) = 49

⇒ 49 + (52 - 2) = 72

⇒ 72 + (62 + 2) = 110

According the pattern of the above series the number series starting from the given number would be as:

⇒ 33

⇒ A = 33 + (22 + 2) = 39

⇒ B = 39 + (32 – 2) = 46

⇒ C = 46 + (42 + 2) = 64

⇒ D = 64 + (52 – 2) = 87

⇒ E = 87 + (62 + 2) = 125

∴ The required number in place of E would be 125.
