Question

What should come in place of the question mark (?) in the given series?

98, 104, 116, 134, 158, ?

This question was previously asked in
RRB ALP 2025 CBT 2 Wiremen Question Paper (28-Jul-2026) (Shift 2)
The correct answer is

188

Look at the differences between consecutive terms.

\(104-98=6\), \(116-104=12\), \(134-116=18\), \(158-134=24\).

The differences increase by 6 each time: 6, 12, 18, 24, so the next difference is 30.

Next term \(=158+30=188\).

Hence, the missing number is 188.
