Question

How do you rewrite each explicit formula in function form a_n = 10 - 2(n-1) ?

Answer 1

To rewrite the explicit formula in function form, we can express a_n in terms of n. The given explicit formula is a_n = 10 - 2(n-1). We can simplify the expression by expanding it and combining like terms.

Step-by-step explanation:

To rewrite the explicit formula in function form, we can express an in terms of n. The given explicit formula is an = 10 - 2(n-1). We can simplify the expression by expanding it and combining like terms.

1. Distribute the -2 to the terms inside the parentheses:
   an = 10 - 2n + 2
2. Combine like terms:
   an = 12 - 2n

Therefore, the rewritten formula in function form is f(n) = 12 - 2n.
