Answer
233 is the thirteenth number in the Fibonacci sequence, where each number is the sum of the two preceding ones. The sequence begins with 0 and 1, and the first twelve numbers are: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89. To find the thirteenth number, we add the twelfth (89) and the eleventh (55), which gives us 233.
