SUCSER  
  
Calculation of the n term of:  
  
	* A succession an  
	* The series with the same general term SN = a1+ a2+ ····· + an  
	* The product Pn = a1·a2· ··· ·an  
  
If some of these results not interests you can disable the corresponding stall  
  
Application: To estimate the possible limit of a succession or series (" perseverance " for high values)  
  
It is necessary to introduce:  
  
	- The " an " expression: Operations with the integer variable n  
		+ - * / ^! (factorial) ( see the text " Successions.txt ")  
	  
	- n: subindex of the term to calculate (ej: n=5 will give the terms a5, S5 and P5)
