To find the values of m and n, we can consider the following steps:

1. Understand the given information:

We are given that [m n] [m] = [1 3] and m + 1 = n.

2. Understand matrix multiplication:

In matrix multiplication, the element in the i-th row and j-th column of the resulting matrix is found by multiplying the corresponding elements of the i-th row of the first matrix with the j-th column of the second matrix and summing the products.

3. Write the equation for matrix multiplication:

[m n] [m] = [1 3]

4. Apply matrix multiplication:

The resulting matrix will have one row and one column, so we can simplify the equation to:

m * m + n * 1 = 1

This simplifies to:

m^2 + n = 1

5. Substitute the value of n:

Since m + 1 = n, we can substitute this into the equation:

m^2 + (m + 1) = 1

6. Simplify the equation and solve for m:

m^2 + m + 1 = 1

m^2 + m = 0

m(m + 1) = 0

7. Find the values of m and n:

From the equation m(m + 1) = 0, we have two possibilities:

m = 0 or m + 1 = 0

If m = 0, then n = m + 1 = 0 + 1 = 1.

If m + 1 = 0, then m = -1 and n = m + 1 = -1 + 1 = 0.

Therefore, the possible values for m and n are:

m = 0, n = 1

or

m = -1, n = 0.
