Question

What is a rule for the sequence below? 1.8, 2.85, 3.90, 4.95, 6

Answer 1

Start with 1.8, then add 1.05 repeatedly

Answer 2

Hello,

The rule is to add each 1.05 each time to the number. 

If you ever want to find the common difference, simply take the second number of the sequence and subtract it by the first (2.85 - 1.8).

Hope this helps =).
