Correct answer is: 6
Explanation:
The pattern is 1 x 2, 2 x 3, 3 x 4, 4 x 5, 5 x 6, 6 x 7, 7 x 8.
So, the missing number is 2 x 3 = 6
Choose the correct altrnative that will continue the same pattern and replace the question mark (?) in the given series.
2, 12, 36, 80, 150, ?

Correct answer is: 252
Explanation:
The series can be seen as : square of a number plus cube of a number
So \(1^3 + 1^2 = 1 + 1 = 2\)
\(2^3 + 2^2 = 8 + 4 = 12\)
\(6^3 + 6^2 = 216 + 36 = 252\)
Choose the correct alternative that will continue the same pattern and replace the question mark (?) in the given series.
1, 5, 14, 30, 55, 91, ?

Correct answer is: 140
Explanation:
The pattern is + 4, + 9, + 16, + 25, + 36, ..... i.e. \(+ 2^2, + 3^2, + 4^2, + 5^2, + 6^2,.....\)
So, missing term = \(91 + 7^2 \)= 91 + 49 = 140.
Choose the correct alternative that will continue the same pattern and replace the question mark (?) in the given series. 120, 99, 80, 63, 48, ?

Correct answer is: 35
Explanation:
The pattern is - 21, - 19, - 17, - 15,.....
So, missing term = 48 - 13 = 35.
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 fill in the blank spaces. 64. 1, 6, 13, 22, 33, (..…)
