Question

Carlos scored 152, 138, and 160 in 3 consecutive

bowling games. His average for these 3 games was
150. What will happen to his average if he scores
198 on his fourth game?

Answer 1

Method 1 :
(152+138+160)÷3 = 150

(152+138+160+198)÷4 = 162

Then his average score will increase

Method 2 :
Since 198 > 150 then the average will increase automatically.
