Answer:
6
Step-by-step explanation:
The mean is calculated as
mean = 
let x be the fourth number, then
= 11 ( multiply both sides by 4 )
38 + x = 44 ( subtract 38 from both sides )
x = 6
The number on the fourth card is 6
n - the first number
n + 11 - the second number
2n + 6 - the third number
81 - the sum of three numbers
The equation:
n + (n + 11) + (2n + 6) = 81
n + n + 11 + 2n + 6 = 81 <em>combine like terms</em>
(n + n + 2n) + (11 + 6) = 81
4n + 17 = 81 <em>subtract 17 from both sides</em>
4n = 64 <em>divide both sides by 4</em>
n = 16
the largest of the tree numbers is the third number 2n + 6.
Substitute the value of n:
2(16) + 6 = 32 + 6 = 38
