SSC CGL (Prelims) Reasoning: Series and Sequences questions with solutions

Q1. Continue the pattern: A3, C5, E7, G9, ?

1. I10
2. J11
3. I11
4. H10

Answer: I11

The letters follow the sequence A, C, E, G, I, increasing by two alphabet positions each time. The numbers follow 3, 5, 7, 9, 11, increasing by 2, so the next term is I11.

Q2. Continue the pattern: E2, G4, I6, K8, ?

1. M10
2. L10
3. N10
4. O10

Answer: M10

The letters follow the sequence E, G, I, K, M, increasing by 2 alphabet positions each time. The numbers follow 2, 4, 6, 8, 10, increasing by 2, so the next term is M10.

Q3. What comes next in the sequence: Z3, W5, T7, Q9, ?

1. O11
2. N11
3. M11
4. P11

Answer: N11

The letters go backward by 3 positions each time: Z, W, T, Q, N. The numbers increase by 2: 3, 5, 7, 9, 11. So the next term is N11.
