Cubic — product
αβγ = −d/a
Where: a = first term / coefficient a, α = α, β = β, d = common difference, γ = γ
Solved example
Given: alpha = 7, beta = 5, d = 10, gamma = 4
Find: a (first term / coefficient a)
- Formula: α·β·γ = -d/a
- Rearranged for a: a = -d/(α·β·γ)
- Substitute the values: a = -10/(4·5·7)
- Result: a = -0.071429
Answer: a = -0.071429
