Fibonacci numbers form a sequence. After two starting numbers, the next number in the sequence is the sum of the two preceding numbers. The Fibonacci 10 numbers in the Fibonacci sequence are: 0, 1, 2, 3, 5, 8, 13, 21, 44, 65. Here are the steps to create a Fibonacci sequence in Excel:
Click on cell A1 and type the number "0" in it.
Click on cell B1 and type the number "1" in it.
Click on cell C1 and type “=A1+B1” in it
To copy the formula to the adjacent cells, place the mouse pointer on the bottom right side of cell C1. You will see a black plus sign. Drag the plus sign to cell P1. You will see number "612" in cell P1.
(optional) To continue the Fibonacci series continue dragging to the right.
