What is the average of 5 consecutive natural number?
Complete step-by-step answer: Average is the sum of observations divided by the number of observations. Therefore 5x+10=5n and after solving this equation we get x=n−2. When we add the next two numbers, we get 5x+10+x+5+x+6=7x+21. Therefore, the new average is 7x+217=x+3.
