Maths question from Laboratory Attendant exam, 2026 by JKSSB

Complete the Number Series: 5, 11, 23, 47, 95, ?

Last updated Jun 13, 2026
Correct Answer: Option B — 191
The correct answer is option B.

To find the next number in the series, we can look at the pattern between the consecutive numbers.

Each number is found by doubling the previous number and then adding one.

Five doubled is ten, and adding one gives eleven.
Eleven doubled is twenty two, and adding one gives twenty three.
Twenty three doubled is forty six, and adding one gives forty seven.
Forty seven doubled is ninety four, and adding one gives ninety five.

To find the next number, we follow the exact same pattern:
Ninety five doubled is one hundred ninety, and adding one gives one hundred ninety one.

So, the missing number is one hundred ninety one, which matches option B.
