Series and Odd Man out Practice Test 8

Question : 5 of 16

Marks: +1, -0

0, 5, 36, 905, 819030

Solution:

Concept:

Each term is obtained by squaring the previous term and adding

5

Explanation:

Start with

0

0^2 + 5 = 5

Next should be

5^2 + 5 = 30

But the given term is

36

, so it breaks the pattern.

Continuing with

30

30^2 + 5 = 905

Then

905^2 + 5 = 819030

Answer:

The odd/wrong term is

36

, so option C is correct.
