below where?
what is the common difference then for the first one?
suppose the terms were

-3,-2,-1,0,...

would that be hard tto figure out? Well, it's the same here:

(t-2)-(t-3) = 1
(t-1)-(t-2) = 1

The common ratios for the 2nd one are found by dividing each term by the previous one:
1,-3/2,2,-5/2
(-3/2)/(1) = -3/2
2/(-3/2) = -4/3
(-5/2)/(2) = -5/4
the ratios are not the same.

sheesh!
i have another question: Identify if the given sequence is arithmetic, geometric, or neither. If the sequence is arithmetic or geometric, then find the next term. and write the nth term.

t^3,t^2,t,1.... is it geometric or arithmetic?
thank you
