Lesson 6-5

Example Use the Look for a Pattern Strategy
EXERCISE Ella started a new exercise program in which she runs every other day and swims every third day. If she runs and swims on the first day of her program, on which days will she have to run and swim during the first 10 days of the program?  

Explore	You know Ella runs and swims on the first day. Then she runs every other day and swims every third day. You need to find which days she will run and swim during the first 10 days.

Plan	Start with running and swimming on the first day and look for a pattern.
	
Solve	Day	Exercise
	1	run, swim
	2
	3	run
	4	swim
	5	run
	6	
	7	run, swim
	8
9	run
10	swim

Ella will run on days 1, 3, 5, 7, and 9. She will swim on days 1, 4, 7, and 10. So, she will run and swim on days 1 and 7.
	
Check	Check the pattern to be sure Ella runs and swims the first day, then runs every other day and swims every third day.
