Suites : 

arith : 
un+1 = un + r
un = up + (n-p)r

montrer suite arith = 

un+1 - un = r 
positif = croissante et inverse

géo = 

vn+1 = q*vn
vn = vp + q(expo)n-p
vn = v0 x q(expo)n

montrer suite géométrique : 
  un+1/un = q
  
cela donne la raison 

asymptote horizontale : x->infini : y --> constante
asymptote verticale : x->a : y ->+infini ou - infini

calculer rang suivant : 
  
prendre la suite un+1 et remplacer un par le rang inférieur à celui qu'on veut calculer
