Dana buys a plant that is 4 inches tall. After one week the plant is 7 inches tall. After a second week the plant is 10 inches tall. At this rate, how tall will the plant be after the fifth week?

19 inches

Step-by-step explanation:

The rate is 3 inches per week. 4+3=7 and 7+3=10. To find the height for the fifth week, all you need to do is add 3 inches every week...

Week 3: 10+3=13

Week 4: 13+3=16

Week 5: 16+3=19

At the same rate, the plant will be 19 inches tall after the fifth week.
