is this sequence arithmetic, geometric or neither?
t subscript n=3/2 (n-1)
-------------
t(n) = (3/2)n - 3/2
The slope is (3/2) and the y-intercept is -3/2
The sequence will start at -3/2 and will have
+3/2 added to form successive terms.
-3/2, 0, 3/2, 6/2, 9/2, ...
The sequence is arithmetic.
-----
Every linear function is this way.
