A: Yes, the number 1,346,269 is a Fibonacci number.

The Fibonacci Sequence is a series of numbers where you add the previous two numbers together. The sum of each is a Fibonacci number.

You start with 0 and add 1 to get the answer 1. You then add 1 + 1 to get 2. Then 2 + 1 to get 3. Then 2 + 3 to get 5, and so on.

To help you see it a little better, the numbers you add together have been color coded:

0 + 1 = 1

1 + 1 = 2

1 + 2 = 3

2 + 3 = 5

3 + 5 = 8

5 + 8 = 13

What would be the next Fibonacci number? If you answered 21, you're right. Here's how: You add 8 + 13, which equals 21. The sum of each set of numbers is a Fibonacci number. There are an infinite number of Fibonacci numbers.

So now that we have a little background on what a Fibonacci number is, let's work through it and try to see if 1,346,269 is a Fibonacci number.

Remember, we start with 0 + 1 = 1 then 1 + 1 = 2 then 1 + 2 = 3 then 2 + 3 = 5, and so on...

**Long Form Fibonacci Test**

0 + 1 = 1

1 + 1 = 2

1 + 2 = 3

2 + 3 = 5

3 + 5 = 8

5 + 8 = 13

8 + 13 = 21

13 + 21 = 34

21 + 34 = 55

34 + 55 = 89

55 + 89 = 144

89 + 144 = 233

144 + 233 = 377

233 + 377 = 610

377 + 610 = 987

610 + 987 = 1,597

987 + 1,597 = 2,584

1,597 + 2,584 = 4,181

2,584 + 4,181 = 6,765

4,181 + 6,765 = 10,946

6,765 + 10,946 = 17,711

10,946 + 17,711 = 28,657

17,711 + 28,657 = 46,368

28,657 + 46,368 = 75,025

46,368 + 75,025 = 121,393

75,025 + 121,393 = 196,418

121,393 + 196,418 = 317,811

196,418 + 317,811 = 514,229

317,811 + 514,229 = 832,040

514,229 + 832,040 = 1,346,269

832,040 + 1,346,269 = 2,178,309

Notice the green equation above. This shows that 1,346,269 IS a Fibonacci number.
