Answer:

160

Explanation:

There are 6 numbers in the set

101 + 119 + 104 + 115 + 109 + x = 6(118)

101 + 119 + 104 + 115 + 109 + x = 708

548 + x = 708

-548 -548

x = 160

Answer:

160

Explanation:

101+119+104+115+109+x=548+x

there are 6 terms including x so divide the sum by 6

(548+x)/6=118

multiply both sides by 6

548+x=708

subtract 548

x=160

hope that helps :)
