## Issue

The prompt for the exercise is as follows:

*Uses a for loop to sum count values from start by increment.
Use: total = sum_count(start, increment, count)
Parameters:
start – the range start value (int)
increment – the range increment (int)
count – the number of values in the range (int)*

What i’ve come up with:

```
def sum_count(start, increment, count):
total = start
for i in range(start, count):
i += increment
total += i
else:
return total
```

When i call and print the function using values 2, 2, 5, the return should be 30, however I am only returning a value of 17. Which part of my code is wrong?

## Solution

If you want to repeat something `x`

times, you can use a loop `for _ in range(x)`

that doesn’t do anything with the value `_`

itself.

Reading the task as

Use a for loop to sum

`count`

values from`start`

by`increment`

means that `count`

is not the upper boundary of the range – that’s what you did – but the number of values to add up. So for `count`

times, increase the `start`

value by `increment`

and take the sum of the values.

```
def sum_count(start, increment, count):
total = 0
for _ in range(count):
total += start
start += increment
return total
```
