Which of the following numbers will replace the question mark (?) in the given series?

225, 221, 214, 201, 176, ?

225, 221, 214, 201, 176, ?

Difference of two constitutive number is increasing from 4,7,13,25

225−221=4

221 − 214 = 7

214 − 201 = 13

201 − 176 = 25

Let's observe the differences between these differences:

7−4=3

13 − 7 = 6

25 − 13 = 12

The second-order differences are:

3,6,12

These differences are doubling, so the next difference should be

12 $$\times$$ 2 = 24

​The next difference between consecutive terms should be

25 + 24 = 49

The last known term is 176 so the next term is:

176 - 49 = 127 

The next number in the series is 127.​

Thus, correct option is (c)
