Let the numbers be 
(0 ≤ y < n), then the mean of the given set is
∑
/ n = 
But the new mean is![S_{2} [/text]<br /><br />= (1 + [tex] x_{1}](https://tex.z-dn.net/?f=+S_%7B2%7D+%5B%2Ftext%5D%3Cbr+%2F%3E%3Cbr+%2F%3E%3D+%281+%2B+%5Btex%5D+x_%7B1%7D+ "S_{2} [/text]<br /><br />= (1 + [tex] x_{1}")
) + (2 + ![x_{2} [/text]) + ... / n<br /><br />=(3/n) + [tex] S_{1}](https://tex.z-dn.net/?f=+x_%7B2%7D+%5B%2Ftext%5D%29+%2B+...+%2F+n%3Cbr+%2F%3E%3Cbr+%2F%3E%3D%283%2Fn%29+%2B+%5Btex%5D+S_%7B1%7D+ "x_{2} [/text]) + ... / n<br /><br />=(3/n) + [tex] S_{1}")
= x + 3/n
∑
But the new mean is
= x + 3/n
