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

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
