Series (SSC CGL 2020 Tier – 1)

The repetitive unit is ‘pqmdh’.
The series will be:
pqmdh / pqmdh / pqmdh / pqmdh

Hence, ‘mphqdpm’ is the correct answer.

Logic: The difference is the square of the consecutive number.
215 + 4² = 231
231 + 5² = 256
256 + 6² = 292
Similarly, 292 + 7² = 341

The repetitive unit is JLPND, and the second letter increases by 1 in each step.
Complete series:
JLPND / JMPND / JNPND / JOPND
