- Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 5 terms are:
1, 2, 3, 5, 8.
Write a program which displays the first 50 Fibonacci numbers.

- If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9.
Write a program which displays all of the multiples of 3 or 5 that are less than 100.
