6.1, 6.9, 7.7, 8.5, 9.3,...

I think it is Geometric, but i don't know how to find the formula

**Steve**, Monday, December 5, 2011 at 12:09pmIf it's geometric, the ratio of successive terms does not change:

6.9/6.1 = 1.131

7.7/6.9 = 1.116

...

not geometric

If it's arithmetic, the difference between terms does not change:

6.9-6.1 = .8

7.7-6.9 = .8

8.5-7.7 = .8

9.3-8.5 = .8

looks like an A.S. to me.
