<h2><em><u>Solution</u></em> : </h2>
let the last number be x
we know,
![\boxed{mean = \frac{sum \: \: of \: \: all \: \: observations}{number \: \: of \: \: observations} }](https://tex.z-dn.net/?f=%20%5Cboxed%7Bmean%20%3D%20%20%5Cfrac%7Bsum%20%5C%3A%20%20%5C%3A%20of%20%5C%3A%20%20%5C%3A%20all%20%5C%3A%20%20%5C%3A%20observations%7D%7Bnumber%20%5C%3A%20%20%5C%3A%20of%20%5C%3A%20%20%5C%3A%20observations%7D%20%7D)
So,
![\hookrightarrow \: 8 = \dfrac{22 + x}{4}](https://tex.z-dn.net/?f=%20%5Chookrightarrow%20%5C%3A%208%20%3D%20%20%5Cdfrac%7B22%20%2B%20x%7D%7B4%7D%20)
![\hookrightarrow \: 8 \times 4 = 22 + x](https://tex.z-dn.net/?f=%20%5Chookrightarrow%20%5C%3A%208%20%5Ctimes%204%20%3D%2022%20%2B%20x)
![\hookrightarrow \: 32 = 22 + x](https://tex.z-dn.net/?f=%20%5Chookrightarrow%20%5C%3A%2032%20%3D%2022%20%2B%20x)
![\hookrightarrow \: x = 32 - 22](https://tex.z-dn.net/?f=%20%5Chookrightarrow%20%5C%3A%20x%20%3D%2032%20-%2022)
![\hookrightarrow \: x = 10](https://tex.z-dn.net/?f=%20%5Chookrightarrow%20%5C%3A%20x%20%3D%2010)
therefore, the last number is 10.
