Q. What will come at the place of question mark ?
2, 7, 27, 107, 427, ?
✅ Correct Answer: (B)
1707
Explanation: The pattern is,
2nd term → 2 +(5 *1^2) = 7
3rd term → 7 +(5 *2^2) = 27
4th term → 27 +(5 *4^2) = 107
5th term → 107 +(5 *8^2) = 427
Missing term → 427 +(5 *16^2) = 1707
2nd term → 2 +(5 *1^2) = 7
3rd term → 7 +(5 *2^2) = 27
4th term → 27 +(5 *4^2) = 107
5th term → 107 +(5 *8^2) = 427
Missing term → 427 +(5 *16^2) = 1707
