What will come in the place of the question mark ‘?’ in the following question? 656, 432, 320, 264, 236, ? Correct Answer 222

Given: 

656, 432, 320, 264, 236, ? 

Calculation:

The series follows the below pattern,

Step 1: difference between the consecutive terms,

(656 - 432), (432 - 320), (320 - 264), (264 - 236)

⇒ 224, 112, 56, 28

The difference is following the below pattern,

224 × 0.5 = 112

112 × 0.5 = 56

56 × 0.5 = 28

28 × 0.5 = 14

⇒ Next term = 236 - 14 = 222

∴ 222 is the next number in the series
