Question

Evaluate each expression for the given values of the variable.

 $3n-1;n=1,2,3,4$

 

Step-by-Step Solution

Answer

The value of the expression is $2,5,8,11$  when $n=1,2,3,4$  respectively.

Step 1. Given Information.

Given expression is $3n-1$  and the values of n are 1, 2, 3, 4.

Step 2. Calculation .

When  :$n=1$

 $\begin{array}{l}3n-1=3\left(1\right)-1\\ 3n-1=3-1\\ 3n-1=2\end{array}$

 

When $n=2$ :

 $\begin{array}{l}3n-1=3\left(2\right)-1\\ 3n-1=6-1\\ 3n-1=5\end{array}$

 

When $n=3$ :

$\begin{array}{l}3n-1=3\left(3\right)-1\\ 3n-1=9-1\\ 3n-1=8\end{array}$

When $n=4$ :

 $\begin{array}{l}3n-1=3\left(4\right)-1\\ 3n-1=12-1\\ 3n-1=11\end{array}$

 

Step 3. Conclusion .

Hence, the value of the expression is  $2,5,8,11$ when $n=1,2,3,4$  respectively.
