Final answer:
The explicit formula given is aₐ = 3ⁿ⁻¹. This formula represents a sequence where the value of each term aₐ is found by raising 3 to the power of ⁿ⁻¹.
Step-by-step explanation:
The explicit formula given is aₐ = 3ⁿ⁻¹. This formula represents a sequence where the value of each term aₐ is found by raising 3 to the power of ⁿ⁻¹. For example, if we want to find the 5th term in the sequence, we substitute ⁿ = 6 into the formula and calculate a₆ = 3⁶⁻¹ = 3⁵, which equals 243.
