Question

What is the common difference between successive terms in the sequence?

Answer 1

Depending on the way you look at the numbers, they are increasing/decreasing by 0.1.

0.36- 0.1 =0.26
0.26-0.1=0.16
0.16-0.1=0.06
0.06-0.1=-0.04
-0.04-0.1=-0.14
(Or vice versa by adding 0.1 starting with -0.14)

Make sense?
