Exemple de sortie écran :

 Compute the 9 first term of the sequence [a_n]  


 a_n : a_1 + (n-1) r 
         1 + (n-1) 1

 a_1 =    +1 
 a_2 =    +2 
 a_3 =    +3 
 a_4 =    +4 
 a_5 =    +5 
 a_6 =    +6 
 a_7 =    +7 
 a_8 =    +8 
 a_9 =    +9 


 Partial sum S_n = [n(n+1)]/2 for the sequence a_n.

 S_n = 45
