Identify the next three terms in the arithmetic sequence 4.2 4.8 5.4 6.0

Question

It is an arithmetic problem

Answer 1

6.6 7.2 7.8

Answer 2

Each (~) is the start of a different line. I guess this system doesn't like the format I tried to do. ~4.2 is your starting amount ~0.6 is the difference between the set of numbers you gave ~4.8-4.2=0.6 ~5.4-4.8=0.6 ~6.0-5.4=0.6 ~(x-1) is for each number you want to find ~You have terms 1-4 and you are looking for terms 5-7 ~So you have the equation y=4.2+0.6(x-1) ~y=4.2+0.6(5-1)=6.6 ~y=4.2+0.6(6-1)=? ~y=4.2+0.6(7-1)=?
