Read the numbers and decide what the next number should come. 8, 6, 9, 5, 10, 4, 11?

A series is a set of numbers following a particular pattern.

Answer: 3 is the next number that should come in the series 8, 6, 9, 5, 10, 4,11, 3.

Let us understand the pattern that is followed in the given series.

Explanation:

In the given series,  8, 6, 9, 5, 10, 4, 11,..., two separate series are combined.

If we notice the alternate numbers we will find the following patterns.

Series 1 = 8, 9, 10, 11.... is the first pattern in which 1 is added to each number;

Series 2 = 6, 5, 4…is the second pattern in which 1 is subtracted from each number.

We need to find the 4th digit in Series 2. 

Thus, we subtract 1 from 4 to get 3 as the next number.

So, the next number after 11 should be 3.

Therefore, 3 is the next number that should come in the series 8, 6, 9, 5, 10, 4,11, 3,...
