In the geomrtric series n=1 we have r = Since r < 8 Then 2n n=1 (-5) n+1 (-5) =+1 2 (-5) n+1 converges and (write in decimal forme Exp 3/4=0.75) 20 n=1 (-5)n +1 In the geomrtric series n=1 we have r = Since r < 8 Then 2n n=1 (-5) n+1 (-5) =+1 2 (-5) n+1 converges and (write in decimal forme Exp 3/4=0.75) 20 n=1 (-5)n +1
