To find the 29th term of the sequence defined by the formula \( a_n = 80n + 79 \), we simply need to substitute \( n = 29 \) into the formula.
\[ a_{29} = 80(29) + 79 \]
Calculating \( 80 \times 29 \):
\[ 80 \times 29 = 2320 \]
Now, add 79 to this result:
\[ a_{29} = 2320 + 79 = 2399 \]
Thus, the 29th term of the sequence is
\[ \boxed{2399} \]
