Answer:

42

Explanation:

let's make the missing number x


mean = (sum \: of \: numbers)/(how \: many \: numbers \: there \: are)


41 = (48 + 33 + x)/(3)

multiply 3 on both sides to get rid of the fraction, 41 × 3 = 123


123 = 48 + 33 + x

simplify the right side, 48 + 33 = 81


123 = 81 + x

subtract 81 on both sides


123 - 81 = x


x = 42
