                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.
1. t-3,t-2, t-1, t...
2. 3/4,1/2,1/3,2/9...
3. 1,-3/2,2,-5/2....

    check for common difference or ratio:
#1: d = 1
#2: r = 2/3
#3: differences: -5/2, +7/2, -9/2, ...
ratios: -3/2, +4/3, -5/4, ...
neither d nor r is constant, so the sequence is not AP or GP

    so one is arithmetic 
number two is geometric
number three is neither?
