Answer 2

The given series are:

To find, the next number of the given sequence (?) is:

Solution:

The pattern follow:

Previous number - 7 × 1, Previous number - 7 × 2, Previous number - 7 × 3, Previous number - 7 × 4, ..........

90 = 97 - 7 × 1

= 97 - 7 = 90

76 = 90 - 7 × 2

= 90 - 14 = 76

55 = 76 - 7 × 3

? = 55 - 7 × 4

= 55 - 28 = 27

∴ The next number of the series (?) = 27
