Answer:
The Fibonacci sequence is a series of integers that begins with a zero, then a one, then another one, and so on.
In other words, the sequence is defined by beginning with the terms 1 and 1, then adding the two preceding terms to generate the following term. For example, if 1+1=2, 1+2=3, 2+3=5, 3+5=8, and so on.
The Fibonacci sequence is given by the sum of the triangles in the diagram. The series begins with 0 and 1 and progresses through the numbers, such as 3 + 5 = 8, and 5 + 8 = 13.
