In order to have a linear equation, you have to write an equation like
The sequence has to start with 3, so we must choose , because this guarantees that when
we have
Now, must be even. In fact, if
is even,
will always be even for every possible
, and
will be odd.
So, for example, you might choose
Which will produce the following sequence:
and so on
Answer: 6 cups of ketchup per cup of mustard
Step-by-step explanation:
