Calculate the Average: Finding Mean of 23, 4, 28, and 1

To solve this problem and calculate the average of the numbers $23$, $4$, $28$, and $1$, follow these steps:

• Step 1: Calculate the sum of the numbers:
  $23 + 4 + 28 + 1 = 56$
• Step 2: Count the number of items in the set.
  There are 4 numbers: $23, 4, 28,$ and $1$.
• Step 3: Divide the sum by the count of numbers to find the average:
  $\frac{56}{4} = 14$

Therefore, the average of the numbers is $14$.
