Homework Statement
Sequence b defined by bn=n(-1)^n, n≥1)
Find a formula for the sequence c defined by Cn= [tex]\Sigma[/tex](i=1)^n b_i )
Homework Equations
Cn= [tex]\Sigma[/tex](i=1)^n b_i )
The Attempt at a Solution
Should I solve for bi sequence first then solve for C?
Cn= [tex]\Sigma[/tex](i=1)^n b_i )=(n*1)^n +(n*1)^n +(n*1)^n +...
