Question

This set of numbers has a mean of 762.

fill in the missing number

148, 926, 1804, ____

Answer 1

I disagree. You determine the mean (average) by totaling up the numbers and dividing by the number of numbers. I feel the answer is 170.

Answer 2

134

Explanation:

148+962+1804+x
`(148+926+1804+x)/(2)=762\\\\148+926+1804+x=2*762\\\\x=2*762-(148+926+1804)\\\\x=134`
