What is the next number in the following series? 16 - 11 - 13 - 8 - 10 - 5 - 7 -

Solution:

Given: Series is 16 - 11 - 13 - 8 - 10 - 5 - 7 -

Consider the first term and the second term, the difference (16 -11) is 5.

The following term is added by +2, we get again a difference of 5 with the following number

Number 8 in the series is added with +2

The result is 10, with a difference of 5, we got 5.

We further added +2 to this result 5 and the final term we get is 7.

Hence, the sequence is subtracted by 5 and added with 2. The sequence is -5, +2, -5, +2, -5, +2 and thus we get 2 as the next number.

Therefore, the next number is 7 - 5 = 2

What is the next number in the following series? 16 - 11 - 13 - 8 - 10 - 5 - 7 -

Summary:

The next number in the following series 16 - 11 - 13 - 8 - 10 - 5 - 7 - is “2”.
