ArithmeticNumber Series & Progressions
Direction: In the following question, a number series is given with one term missing. Choose the correct alternative that will continue the same pattern and answer on the OMR Answer Sheet by filling the circle.
2, 7, 27, 107, 427, ?
- a.1262
- b.1707
- c.4027
- d.4207
Answer: (B) 1707
Each term is 4 times the previous one minus 1: 2 × 4 − 1 = 7, 7 × 4 − 1 = 27, 27 × 4 − 1 = 107 and 107 × 4 − 1 = 427. So the next term is 427 × 4 − 1 = 1707. The other options do not follow this rule.
