SUMMARY

The series Σn/[(n+1)(n+2)(n+3)] can be solved by decomposing it into partial fractions. The first step involves rewriting the expression as A/(n+1) + B/(n+2) + C/(n+3), where A, B, and C are constants that need to be determined. This method simplifies the series and allows for easier summation. The discussion emphasizes the importance of partial fraction decomposition in solving complex series.

PREREQUISITES

I guess the first step is to rewrite this into
A/(n+1) + B/(n+2) + C/(n+3)
where A, B, C are numbers.
