Recusive- f(n)=f(n-1)+_____ f(1)=__
Eq. of the first diff linear
Explicit- compare to perfect square (x^2)

Exponetial

ryanc3231 — 2017-06-05 17:52:15 UTC

Explicit- f(n)+a(b)^x
b=common ratio
a=zero term
Recursive- f(n)+f(n-1)x____ f(1)+___

Linear

ryanc3231 — 2017-06-05 17:52:21 UTC

Explicit- f(n)+m x n+b
b=zero term
Recursive- f(n)=f(n-1)+______ <---- common diff
f(1)___
