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:

- The General formula of any AP is .
- 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 plus2 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

a_{1} = 28

d = 2

We know that general formula is a_{n} = a_{1} + (n - 1)d

So,

Step 2 of 2:

Now, Cost of renting for 8 days will be

_{1}= 28

We know that general formula is a

_{n}= a

_{1}+ (n - 1)d

So,

Step 2 of 2:

Now, Cost of renting for 8 days will be
