7. Identify the explicit formula for the sequence given by the recursive formula

 B) f(n) = 30 - 8(n - 1)

Step-by-step explanation:

Explicit formula is of the form:    where

Given: f(1) = 30  --> this represents the first term = 30

          f(n - 1) - 8   --> this means the previous term minus 8 thus d = -8

= 30 + (-8)(n - 1)

    = 30 - 8(n - 1)

the thermometer is precise but not accurate
