N-3, n-2, n-1, n and the sum is

4n-6=198 add 6 to both sides

4n=204 divide both sides by 4

n=51

Answer:

x = 3

Step-by-step explanation:

Given

f(x) = - 10x + 45 and f(x) = 15, then equating gives

- 10x + 45 = 15 ( subtract 45 from both sides )

- 10x = - 30 ( divide both sides by - 10 )

x = 3
