In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Individual numbers in the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn . The sequence commonly starts from 0 and 1, although some authors start the sequence from 1 and 1 or sometimes (as did Fibonacci) from 1 and 2. Starting from 0 and 1, the first few values in the sequence are: Web6 apr. 2024 · Complete step-by-step answer: It is given that A = {1, 2} and B = {3, 4} We know that the number of elements in A is n (A)=2 and that of B is n (B) = 2.
