Question : Directions: Which number will replace the question mark (?) in the following series?
37, 39, ?, 242, 970, 4852
Option 1: 80
Option 2: 122
Option 3: 108
Option 4: 160
Correct Answer: 80
Solution :
Given:
37, 39, ?, 242, 970, 4852
Multiply each number by consecutive natural numbers and add 2 to the resultant to find the next number in the series.
(37 × 1) + 2 = 39; (39 × 2) + 2 = 80; (80 × 3) + 2 = 242; (242 × 4) + 2 = 970; (970 × 5) + 2 = 4852
So, the missing term is 80. Hence, the first term is correct.
