Correct Answer: 144


Solution : Given:
14, 22, 37, 61, 96, ?

Subtracting 1 from the squares of consecutive natural numbers (starting from 3) and then adding the resultant to the previous number, to get the next number in the series.
14 + {(3) 2 – 1} = 14 + {9  – 1} = 14 + 8 = 22
22 + {(4) 2 – 1} = 22 + {16  – 1} = 22 + 15 = 37
37 + {(5) 2 – 1} = 37 + {25  – 1} = 37 + 24 = 61
61 + {(6) 2 – 1} = 61 + {36  – 1} = 61 + 35 = 96
96 + {(7) 2 – 1} = 96 + {49  – 1} = 96 + 48 = 144

So, the required number is 144. Hence, the third option is correct.
