terminating decimal
Step-by-step explanation:
A terminating decimal is usually defined as a decimal number that contains a finite number of digits after the decimal point.
The Gauss-Jordan elimination method different from the Gaussian elimination method in that unlike the Gauss-Jordan approach, which reduces the matrix to a diagonal matrix, the Gauss elimination method reduces the matrix to an upper-triangular matrix.
<h3>
What is the Gauss-Jordan elimination method?</h3>
Gauss-Jordan Elimination is a technique that may be used to discover the inverse of any invertible matrix as well as to resolve systems of linear equations.
It is based on the following three basic row operations that one may apply to a matrix: Two of the rows should be switched around. Multiply a nonzero scalar by one of the rows.

Answer:
25,31,37
Step-by-step explanation:
n should be positive integer number. The three numbers in both sequences have different term number n but same value. We can equalize each nth term in the question to "a" which represents one of the three numbers.
a=2n-1, then n=(a+1)/2
a=3n+1, then n=(a-1)/3
remember the two n above are different but both should be positive integer. That means, we have to find the "a" number that gives me an integer n for the first equation. The possible numbers between 20 to 40 are 22,25,28,31,34,37,40.
The possible numbers for the second equation are 21,23,25,27,29,31,33,35,37,39.
Now find the common numbers between the two sets above. They are 25,31,37
When you’re given two coordinates, recall that the coordinates are in the format of (x, y).
Knowing this, you know that in the coordinate (2, -2) the value of x equals 2 and the value of y equals -2.
Thus, we can put these variables into the two given equations and see if the equations hold.
-2 < -2(2) + 3
-2 < -4 + 3
-2 < -1
As you can tell, the first equation holds since -1 is bigger than -2.
Onto the second equation.
-2 ≥ 2 - 4
-2 ≥ -2
As you can tell, the second equation holds as well since -2 equals -2.
This means that yes, (2, -2) is a valid solution.
