Question 1 of 25

1. Question
1 points

Category: Reasoning
Direction : In each of the following questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.

1, 1, 4, 8, 9, 27, 16, ?
- 32
- 64
- 81
- 256
Correct

The series consists of squares and cubes of consecutive natural numbers i.e.
$1^{2}, 1^{3}, 2^{2}, 2^{3}, 3^{2}, 3^{3}, 4^{2}, . . . . . . .$
So missing term =
$4^{3} = 64 .$

Category: Reasoning
Direction : In each of the following questions, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and replace the question mark in the given series.

3, 8, 13, 24, 41, ?
- 70
- 75
- 80
- 85
Correct

The pattern followed is :

nth term + (n + 1)th term + (n + 1) = (n + 2)th term.

Thus, 1st term + 2nd term + 2 = 3rd term;

2nd term + 3rd term + 3 = 4th term and so on.

So, missing term = 6th term = 4th term = 5th term + 5 = 24 + 41 + 5 = 70.

Incorrect

The pattern followed is :

nth term + (n + 1)th term + (n + 1) = (n + 2)th term.

Thus, 1st term + 2nd term + 2 = 3rd term;

2nd term + 3rd term + 3 = 4th term and so on.

So, missing term = 6th term = 4th term = 5th term + 5 = 24 + 41 + 5 = 70.
