to calculate average, you simply add all the data, and divide it by the number of data.
so in this case, let the third game be y.
so,
(154 + 188 + y)/3 = 170
154 + 188 + y = 510
y = 168
so he must bowl at least 168 in his third game

154 + 188 + x /3 = 170
342 + x /3 = 170
342 + x = 510
x = 168

Ben must bowl at least 168 to have an average of at least 170
