Answer :
Right now, after 5 games, his average is
(1/5) (210 + 225 + 254 + 231 + 280) = (1/5) (1,200) = 240
In order to maintain this exact average through the sixth game,
he must roll a 240 .
(1/5) (210 + 225 + 254 + 231 + 280) = (1/5) (1,200) = 240
In order to maintain this exact average through the sixth game,
he must roll a 240 .
