Concept:
The sequence consists of prime numbers arranged in increasing order.
Step 1: Identify the terms.
\[
3,\ 7,\ 13,\ 19,\ 29,\ 37
\]
All are prime numbers.
Step 2: Continue the prime sequence.
The prime numbers after \(37\) are
\[
41,\ 43,\ 47,\ldots
\]
Examining the pattern more carefully, the given series selects alternate prime numbers:
\[
3,\ 7,\ 13,\ 19,\ 29,\ 37,\ 43.
\]
Therefore the next term is
\[
\boxed{43}.
\]
