A relation on a set \(A\) is an equivalence relation if it is reflexive, symmetric, and transitive. The characteristic equation for the above recurrence relation is −, Three cases may occur while finding the roots −, Case 1 − If this equation factors as $(x- x_1)(x- x_1) = 0$ and it produces two distinct real roots $x_1$ and $x_2$, then $F_n = ax_1^n+ bx_2^n$ is the solution. Solution to the first part is done using the procedures discussed in the previous section. trying to find things to improve my web site!I suppose its ok to use a few of your Many different systems of axioms have been proposed. They are the fundamental building blocks of Discrete Math and are highly significant in today’s world. Some people mistakenly refer to the range as the codomain(range), but as we will see, that really means the set of all possible outputs—even values that the relation does not actually use. c) a has the same first name as b. of the form $c.x^n$, a reasonable trial solution of at will be $Anx^n$, After putting the solution in the recurrence relation, we get −, $An5^n = 3A(n – 1)5^{n-1} + 10A(n – 2)5^{n-2} + 7.5^n$, $An5^2 = 3A(n - 1)5 + 10A(n - 2)5^0 + 7.5^2$, Or, $25An = 15An - 15A + 10An - 20A + 175$, The solution of the recurrence relation can be written as −, Putting values of $F_0 = 4$ and $F_1 = 3$, in the above equation, we get $a = -2$ and $b = 6$. A recurrence relation is an equation that recursively defines a sequence where the next term is a function of the previous terms (Expressing Fn as some combination of Fi with i
