What is the general format of a geometric explicit equation?
t(n) = dn + t(0)
t(n) = t(0) x m^n
t(n + 1) = t(n) x m
t(n + 1) = t(n) x m; t(1) = 1st term

What is the general format of a geometric recursive equation?
t(n + 1) = t(n) + d; t(1) = 1st term
t(n) = t(0) x m^n
t(n + 1) = t(n) x m
t(n + 1) = t(n) x m; t(1) = 1st term

Write the explicit equation for the following sequence: 2, 6, 18, 54, ...
t(n + 1) = t(n) x 3; t(1) = 2
t(n) = 2 x 3^n
t(n) = (2/3) x 3^n
t(n) = 3n - 2

Write the recursive equation for the following sequence: 100, 50, 25, 12.5, ...
t(n + 1) = t(n) x 1/2; t(1) = 100
t(100) = t(50)
t(n + 100) = t(50) x 1/2
t(n) = 200 x (1/2)^n
