Tammy uses 1 3/4 cups of laundry detergent. The number of loads is 4
<u>Solution:</u>
Given that, Tammy uses 1 3/4 cups of laundry detergent per load.
When she was finished doing laundry one day.
She noticed that she had used 7 cups of laundry detergent.
We have to find how many loads did she do?
Now, we know that, Total cups used can be written as:
<em> </em>number of loads x number of cups per each load = total cups used.

Hence, the number of loads are 4.
The sequence of numbers decrease by 6 each time, so we can write:
f(1) = 5
f(2) = -1
f(3) = -7
f(1) - f(2) = 6
or:
f(2) = f(1) - 6
which means:
f(n + 1) = f(n) - 6
