Question : Directions: In the following question a series is given, with one number missing. Select the missing number from the given series. 1, 4, 15, 64, ?
Option 1: 285
Option 2: 315
Option 3: 325
Option 4: 375
Correct Answer: 325
Solution : Given: 1, 4, 15, 64, ?
Multiply and add the natural numbers starting from 2 to the previous term to get the next term of the series – (1 × 2) + 2 = 4; (4 × 3) + 3 = 15; (15 × 4) + 4 = 64; (64 × 5) + 5 = 325
So, 325 is the missing term of the given series. Hence, the third option is correct.
