I got a problem that states which graph represents the sequence of 1,2.5,4,5.5,7..
Should the graph start at 1,1 or 0,1?
Answered by drwls
The sequence's nth term, An, is 1 + 1.5(n-1)
= 1.5n -0.5

If you are graphing An vs n, start at (1,1)

You get a straight line through that point with slope = 1.5
