Question

The cost to rent a bike is $$$ 28 for the first day plus $$$ 2 for each day after that. Write an explicit formula for the rental cost for n days. What is the cost of renting a bike for 8 days?

hint Hint:

The General formula of any AP is $a subscript n equals a subscript 1 plus left parenthesis n minus 1 right parenthesis d$ .

A sequence is said to be arithmetic if the common difference is always constant.

The correct answer is: a8 = 42

Explanation:

We have given a cost of rent of bike $$$ 28 for the first day plus $$$ 2 for each day after that.

We have to write an explicit formula for the rental cost for n days and cost of renting bike for 8 days.

Step 1 of 2:
We have given first day cost is $$$ 28 and for each more day $$$ 2 will be charged
Here
a₁ = 28
d = 2
We know that general formula is a_n = a₁ + (n - 1)d
So,

Step 2 of 2:
Now, Cost of renting for 8 days will be
