Question

The results of an experiment that Lacey is doing are recorded in the table below. Day Number of Amoeba 1 21 2 22 3 23 How many amoebas will be present on the fourth day? 2 4 6 16

Answer 1

Lets rewrite the information above :

Day 1 : 21

Day 2 : 22

Day 3 : 23

From the table we see that the number of Amoeba increases by 1 each day.

Therefore on the fourth day it will also increase by 4

Day 4 is thus :

23 + 1 = 34

Answer : 24
