The Correct Option is B
Solution and Explanation
The pattern in the series is increasing by multiplying the previous term by 2 and adding 1:
1 * 2 + 3 = 5
5 * 2 + 3 = 13
13 * 2 + 3 = 29
29 * 2 + 3 = 61
61 * 2 + 3 = 103.
Thus, the next number in the series is "103".
1 * 2 + 3 = 5
5 * 2 + 3 = 13
13 * 2 + 3 = 29
29 * 2 + 3 = 61
61 * 2 + 3 = 103.
Thus, the next number in the series is "103".
