the determinant is calculated using the formula ad - bc where a,b,c and d are the following positions in the matrix [a   b                                                                                  ...

e.g : 2,4,6,8..

the formula for the sequence can be found by using a+(n-1)d , where a is the first number in the sequence and d is the diffenece between the adjacent numbers in the sequence. so a =...

Well, for numbers, we have a number axis which is a straight line (like this [...]) and it is divided into more pieces, of one unit each. We begin to draw this axis by placing zero in the middle (like thi...
