In this case, we have the following set of numbers: 1, 2, 3, x, 4, 5.

Let's calculate the sum of these numbers:
1 + 2 + 3 + x + 4 + 5 = 15 + x

According to the given information, the mean is 10. We can set up the equation:

(15 + x) / 6 = 10

Now, let's solve this equation to find the value of x:

15 + x = 10 * 6
15 + x = 60
x = 60 - 15
x = 45

Therefore, the value of x that satisfies the condition is 45.

1,2,3,x,4,5 this set has the mean is 10.
.•. (1 + 2 + 3 + x + 4 + 5)/6 = 10 {formula for calculating the mean}
Cross multiply
15 + x = 60
Collect like terms
x = 45
