We have sequence equation
.
In this case n is a natural number (1, 2, 3, ...).
So start inserting and computing value of
given that you know the value of n and a.
(first term)

Hope this helps.

Answer:
0.015x
Step-by-step explanation:
The amounts earned at the different rates are ...
at 2%: 0.02x
at 3.5%: 0.035x
The difference in earnings is ...
0.035x -0.02x = 0.015x
There is a hole at x=4 because the top factors to (x-4)(x+3)
in the end we get
f(x)=(x-4)(x+3)/(x-4)
the (x-4) cancels out and we get
f(x)=x+3
so baiscally f(x) is y=x+3 but with a hole at (4,7)
one way is to make a piecewise function defined as(x^2-x-12)/(x-4) for all x≠4 and defined as 7 for x=4
or, to just do f(x)=x+3
