Q. Which number should come next in the series 1, 2, 3, 10, ___
✅ Correct Answer: (B)
99
Explanation: The logic for the given series is the square of the appearing number and addition of 1 at first position and subtraction of 1 at second position. This simply means that -
1^2 + 1 = 2
2^2 - 1 = 3
3^2 + 1 = 10
Similarly, the number after 10 is -
10^2 - 1 = 99
