Question

If the range of the numbers below is 8, what could the missing number be? 1 & 3

Answer 1

To achieve a range of 8 in the given set (1, 3, ?), the missing number is 11. This maintains the difference between the maximum and minimum values, ensuring the desired range.

If the range of the given numbers is 8, we can calculate the range as the difference between the maximum and minimum values. Let's assume the missing number is x:

`\[ \text{Range} = \text{Max} - \text{Min} = 8 \]`

In this case, the maximum value is 3, and the minimum value is 1:

8 = 3 - 1

Now, solve for the missing number (x):

x = 3 + 8 = 11

So, the missing number could be 11 for the range to be 8.

The complete question is:
