Question 13

Explanation

The number sequence follows a combination of two alternating addition patterns. Observing the differences between terms reveals a repeating cycle:

The pattern consists of two groups of differences:

1. First group: $+2$, $+4$, $+6$
2. Second group: $+1$, $+3$, $+5$

After the term $36$, the cycle returns to the second group pattern, starting with $+1$.

Thus, the next term is:

Therefore, the correct number to complete the sequence is $37$.
