Sarita has a book containing 500 pages and reads 20 pages every day. In 15 days, she reads 20 multiplied by 15, which equals 300 pages. Therefore, the number of pages left becomes 500 minus 300, which equals 200 pages. If n represents the number of days, then the number of pages remaining can be written as 500 minus 20n. This expression forms a linear pattern because the number of pages decreases by the same amount every day.
