Question

Which of the following numbers will replace the question mark (?) in the given series?
165, ?, 195, 210, 225, 240

A.

180

B.

185

C.

192

D.

172

Correct option is A

Series: 165, ?, 195, 210, 225, 240
The difference between consecutive terms in the sequence we have:
195−?
210−195=15
225−210=15
240−225=15
We can observe that the series increases by 15 with each term after the missing number.
So, to find the missing number, we can subtract 15 from 195:
195−15=180
Correct answer: (a) 180.
