Question

The pattern below starts with the number 20 and follows a rule. 5,15,35,75,155

What is the rule for the pattern?

Answer 1

You want us to make one following that rule but starting with 20? Cause that would be
20, 45, 95, 195 (do the number times 2 then add 5.) So how it was 5 then do 5x2 which is 10+5 you get 15 then 15x2 30+5= 35 and so on

Answer 2

5,10,20,40,110 that I think is the answer hope this helps
