Luisa ran 3 miles on the 3rd day of a month, and she repeated her run every 4 days for the rest of the month. What equation describes the sequence of days of that month that Luisa ran?

--- I have no idea how to begin this.

4n-1

To find the equation that describes the sequence of days that Luisa ran, we need to first determine the pattern in which she ran.

Luisa ran 3 miles on the 3rd day of the month. Then, she repeated her run every 4 days for the rest of the month. This means that she ran every fourth day after the 3rd day.

We can start by listing the days on which Luisa ran:
Day 3
Day (3 + 4) = Day 7
Day (7 + 4) = Day 11
Day (11 + 4) = Day 15
and so on...

From this pattern, we can see that Luisa runs on every day that is a multiple of 4, starting from the 3rd day.

So, the equation that describes the sequence of days that Luisa ran can be written as:

Day = 4n + 3

Here, n represents the number of times Luisa repeated her run after the 3rd day.

For example, if we substitute n = 0 in the equation, we get:
Day = 4(0) + 3
Day = 3

This tells us that on the 0th repetition (or the 1st run), Luisa ran on the 3rd day.

If we substitute n = 1:
Day = 4(1) + 3
Day = 7

This tells us that on the 1st repetition (or the 2nd run), Luisa ran on the 7th day.

By substituting different values of n, we can determine the days on which Luisa ran during the month.

Does the month have 30 days?

She ran on the 3rd, 7th, 11th, 15th, 19th, 23rd, 27th and 31st?

3+((x-3)/4)*3=Total Miles

Fill in X with number of days in month

3+((x-3)/4)*3=Total Miles

Fill in X with number of days in month

OMG, I need help on this question too...

It asks for sequence of days not miles though...

Luisa ran 3 miles on the 3rd day of a month, and she repeated her run every 4 days for the rest of the month. What equation describes the sequence of days of that month that Luisa ran?

I have This Question too SOmeone just answer it

This question was easy
