Fibonacci cov naj npawb

Fibonacci cov naj npawb yog ib ntu ntawm cov lej uas pib nrog tus lej 0 thiab 1, thiab txhua tus nqi tom qab yog cov lej ntawm ob tus dhau los.

Fibonacci Sequence Formula

Piv txwv li:

• F₀ = 0
• F₁ = 1
• F₂ =F₁+F₀ = 1 + 0 = 1
• F₃ =F₂+F₁ = 1 + 1 = 2
• F₄ =F₃+F₂ = 2 + 1 = 3
• F₅ =F₄+F₃ = 3 + 2 = 5

Tshooj Golden

Qhov piv ntawm ob tus lej Fibonacci sib law liag mus rau qhov kub piv:

qhov twg φ yog golden piv = (1 + √5) / 2 ≈ 1,61803399

Feem ntau, tus nqi no suav nrog 1,618 (lossis 1,62). Thiab nyob rau hauv qhov sib npaug feem pua, qhov kev faib ua feem zoo li no: 62% thiab 38%.
