Question

Cathy is putting stickers in a book. She puts 3 stickers on the first page, 6 stickers on the second page, 9 stickers on the third page, and 12 stickers on the fourth page. If this pattern continues, then how many stickers will Cathy put on the fifth page?

• A. 15
• B. 20
• C. 10
• D. 12

Answer 1

The correct option is A 15

Let us look at the pattern of the stickers.

From the table, we find:

Number of stickers on a particular page
= 3 $\times$ Page number

$\therefore$ Number of stickers on page 5
= 3 $\times$ 5
= 15

Thus, Cathy will put 15 stickers on page 5.
