Question

Jonas has the following data: 2, 5, x, 2, 4, 3. if the average is 3, what number should be instead

Answer 1

Number should be 2 instead of x .

Step-by-step explanation:

Here we have , Jonas has the following data: 2, 5, x, 2, 4, 3. if the average is 3, We need to find  what number should be instead x . Let's find out:

We know that

$Average = \frac{(x_1+x_2+x_3+...........+x_n)}{n}$

Where $x_1, x_2,x_3,.....,x_n$ is terms and n is the number of terms . Let's find average for 2, 5, x, 2, 4, 3 which is 3 :

⇒ $Average = \frac{(x_1+x_2+x_3+...........+x_n)}{n}$

⇒ $3 = \frac{(2+5+x+2+4+3)}{6}$

⇒ $3(6) = \frac{(16+x)}{6}(6)$

⇒ $18= 16+x$

⇒ $x=2$

Therefore , Number should be 2 instead of x .
