These are Fibonacci numbers.
God created the world with numbers. The most important of them, found throughout nature in the form of the golden ratio, are the Fibonacci numbers: 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, 233, 377, 610, 987, and so on, approximately 1600, 2600, 4200, 6800, 11000. Each of them is formed as the sum of the two previous ones, and the golden ratio is approximately equal to the ratio of adjacent numbers or numbers separated by one. The development of the idea of the golden ratio is harmonics, the ratio of Fibonacci numbers separated by several steps. For example, 21:3=7, 55:5=11, 144:8=18, 377:13=29, 987:21=47. Moreover, the number of steps is equal to the number of the harmonic in their general sequence: 1, 3, 4, 7, 11, 18, 29, 47, 76, 123, 199, 322, 521, 843, 1364, etc. And each harmonic is also equal to the sum of the two previous ones.

I suggest we think about it together
