Yes it's called look and say sequence. To generate the next term you have to "say" the digits in the term and write them down accordingly.

For example, first term is $1$. So how many $1$'s ? One $1$. So the next term is $11$, then now say the term, it's two $1$'s, so the next term $21$ and etc.

This is the look-and-say sequence. You can also find it on OEIS.
