Let's analyze the pattern in the sequence $1, 2, 2, 4, 3, 6, 4, 8, 5, 10$ and determine the next number.

This sequence seems to be alternating between two interleaved sequences:

• First sequence (odd-positioned terms): $1, 2, 3, 4, 5$
• Second sequence (even-positioned terms): $2, 4, 6, 8, 10$

The odd-positioned terms are increasing by 1 each time, and the even-positioned terms are increasing by 2 each time.

Predicting the next term:

• The next odd-positioned term after 5 should be $6$.
• The next even-positioned term after 10 should be $12$.

So, the sequence should continue as $6, 12$.

Thus, the next number in the sequence is 6.
