AM of three numbers

The number 2010 can be written as the sum of 3 consecutive natural numbers. Determine the arithmetic mean of these numbers.


x =  670


 2010=a+(a+1)+(a+2)  3a=2007  x=a=669 x=a+1=669+1=670 \ \\ 2010=a + (a+1)+(a+2) \ \\ \ \\ 3a=2007 \ \\ \ \\ x=a=669 \ \\ x=a+1=669+1=670

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
