Answer:

Step-by-step explanation:

84-90=90-96=96-102=102-108=-6

its a sequence where A(1)=84 n A(n+1)-A(n)=6

A(n)=84+(n-1)*6; n=1,2,3,4,5

Answer:

f(x) = 84 + 6x where x=0, 1, 2, 3, 4, ...

Step-by-step explanation:

Given 84, 90, 96, 102, 108, ...

the numbers are a sequence with 84 as the initial value and in increment of 6s. So the function can be written as:

f(x) = 84 + 6x where x=0, 1, 2, 3, 4, ...
