Final answer:
The explicit formula for the nth term in the given sequence 13, 15, 17, ... is an = 13 + 2(n-1).
Step-by-step explanation:
The given sequence is 13, 15, 17, ...
To find the explicit formula for the nth term, we observe that the first term is 13 and each subsequent term is 2 more than the previous term.
So, the explicit formula for the nth term is an = 13 + 2(n-1).
