Exemple de sortie écran :

 Compute the 9 first term of the sequence [a_n]  


 a_n : a_1 + (n-1) r 
        -4 + (n-1) 3

 a_1 =    -4 
 a_2 =    -1 
 a_3 =    +2 
 a_4 =    +5 
 a_5 =    +8 
 a_6 =   +11 
 a_7 =   +14 
 a_8 =   +17 
 a_9 =   +20 


 Partial sum S_n = [a_1 n + [(n-1)*r)*n] /2 for the sequence a_n.

 S_n = 72
