Final answer:
The explicit formula for the arithmetic sequence is 10 + 3(n²). To write this formula in function form, replace the exponent with the variable n. The function form is f(n) = 10 + 3(n²).
Step-by-step explanation:
The explicit formula for the arithmetic sequence is represented by the equation aⁿ = 10 + 3(n²).
To write this formula in function form, we simply replace the exponent ⁿ with the variable n. Therefore, the function form of the explicit formula is f(n) = 10 + 3(n²).
