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:
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
4x+1
sum= addition
one=1
and= plus
product of four and a number: when we say a number we usually use the variable x. 4(x)= 4x
put together: 4x+1 (no equal sign needed)
