Sequence Formulas
Arithmetic: aโ = aโ + (nโ1)d | Sโ = n/2 ร (aโ + aโ)
Geometric: aโ = aโ ร rโฟโปยน | Sโ = aโ(rโฟโ1)/(rโ1), rโ 1
Fibonacci: F(n) = F(nโ1) + F(nโ2), F(1)=1, F(2)=1
Geometric: aโ = aโ ร rโฟโปยน | Sโ = aโ(rโฟโ1)/(rโ1), rโ 1
Fibonacci: F(n) = F(nโ1) + F(nโ2), F(1)=1, F(2)=1
Key Differences
- Arithmetic: Each term differs by a constant amount (e.g., 2, 5, 8, 11โฆ d=3)
- Geometric: Each term multiplied by a constant ratio (e.g., 3, 6, 12, 24โฆ r=2)
- Fibonacci: Each term is the sum of the two preceding terms
