NIMCET 2015 — Reasoning PYQ

The terms are $4,10,16$.

• $4+6=10$

• $10+6=16$

• Logic: Add $6$ to the previous term.

2. Second Sub-series (Positions 2, 5, 8):

The terms are $7,\dots ,19$.

Let the missing term be $x$.

• If we follow a similar logic of adding a constant: $7+6=13$ and $13+6=19$.

• Logic: Add $6$ to the previous term. Thus, $x=13$.

3. Third Sub-series (Positions 3, 6):

The terms are $25,20$.

• $25-5=20$

• Logic: Subtract $5$ from the previous term.

Conclusion:

By analyzing the second sub-series, we find that the missing number is $13$.

Correct Option: (a) 13
