Question

Dan sees the following number pattern on the chalkboard.

5, 10, 20, 40, ...
What is the rule for this pattern?

Answer 1

the rule is that each time you go up you add the number by itself to get another for example 5, 10 we now know that 5+5 = 10 continuing 5, 10, 20

10+10 = 20

Answer 2

multiply by 2

Explanation:

5x2=10

10x2=20
