Answer

$49$ is the 5th term of the sequence.

Steps

Step 1 ：Given the formula for the nth term of a sequence: $T (n) = 8 n + 9$

Step 2 ：Substitute n = 5 to find the 5th term: $T (5) = 8 (5) + 9$

Step 3 ：Calculate the value: $T (5) = 40 + 9$

Step 4 ： $T (5) = 49$

Step 5 ： $49$ is the 5th term of the sequence.
