Question

Evaluate each expression for the given values of the variable.

$3n-1;n=1,2,3,4$

Short answer

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

Step-by-step solution

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.
