Answer:

The included number is 34

Step-by-step explanation:

Formula used:

Mean=\frac{\Sigma{x}}{n}

Let the included number be k

Given:

Mean of 5 numbers = 22

\frac{\Sigma{x}}{5}=22

\Sigma{x}=22*5

\Sigma{x}=110

when one more nuimber is included

New\:\Sigma{x}=110+k

Now,

New\:Mean=\frac{New\:\Sigma{x}}{6}

24=\frac{110+k}{6}

24*6=110+k

144=110+k

k=34

Therefore, the included number is 34
