... The above equation implies that b2 is even and hence b is even. Since we know a is even this means that a and b have 2 as a common factor which contradicts the assumption that a and b have no common factors. ...

... For example, let's add the number -2 + 7i to the number 9 - 4i: (-2 + 7i) + (9 - 4i) = (-2+9) + (7i - 4i) = (-2+9)+(7-4)i = 7 + 3i Another example, let's add the number 2 - 5i to the number -3 - 4i: (2 - 5i) + (-3 - 4i) = (2+-3) + (-5i+ - 4i) = (2-3)+(-5-4)i = -1 -9i Subtracting complex numbers is j ...

... to 0 as n tends to infinity. So, for some subscript N , 0 < |xn | < 1 for every n > N , thus, only a finite number of the xn ’s will be integers. Consequently, the only way to obtain an infinite number of integer values in the sequence is to have x1 = x2 . In this case, xn = x1 for every n, so unles ...
