Question
There are three numbers: 4, 26 and 18. A fourth number creates a group average of 12. What is this fourth number?0381214
Solution
To find the fourth number, you first need to find the total sum of the four numbers. Since the average is 12, the total sum would be 12 * 4 = 48.
Next, you add up the three given numbers: 4 + 26 + 18 = 48.
Finally, you subtract the sum of the three given numbers from the total sum to find the fourth number: 48 - 48 = 0.
So, the fourth number is 0.
