Final answer:
The explicit formula for the nth term of the sequence 5, 25, 125 is aₙ = 5^(n-1).
Step-by-step explanation:
The explicit formula for the nth term of the sequence 5, 25, 125 is an = 5n-1.
This means that to find the nth term, you raise 5 to the power of (n-1). For example, if you want to find the 4th term, you would substitute n=4 into the formula: a4 = 54-1 = 53 = 125.
