Question

Which will replace the question mark in the given series?
120, 143, 168,?

A.

194

B.

193

C.

191

D.

195

Correct option is D

Given series:
120, 143, 168, ?
Observing the differences between consecutive terms:
143 − 120 = 23
168 − 143 = 25
We see an increasing pattern in the differences:
23, 25, ?
The next difference should follow the same pattern. Since the differences are increasing by 2, the next difference should be: 27
Find the missing term
168 + 27 = 195
The missing number is 195, so the correct answer is: (D) 195
