What comes next in the series?

BDF, GIK, LNP, ?

This question was previously asked in
SSC CHSL 2025 Tier 1 Question Paper (21-Nov-2025) (Shift 1)
The correct answer is

QSU

This is a letter series where each group of three letters follows a fixed internal spacing and each group starts a fixed distance after the previous one.

Look inside the first group BDF: positions are B=2, D=4, F=6, so the letters go up in steps of 2.

The same holds for GIK (7, 9, 11) and LNP (12, 14, 16); every group is three letters with a gap of 2 between them.

Now track the first letter of each group: B(2), G(7), L(12). Each starting letter jumps forward by 5.

So the next group must start at position \(12+5=17\), which is Q.

From Q, add 2 to get the second letter: \(17+2=19\), which is S.

Add 2 again for the third letter: \(19+2=21\), which is U.

Combining gives QSU, which matches the highlighted option. Hence the answer is QSU.
