If α, β are natural numbers such that 100α - 199β = (100)(100) + (99)(101) + (98)(102) + ... + (1)(199), then the slope of the line passing through (α, β) and origin is:
If α, β are natural numbers such that 100α - 199β = (100)(100) + (99)(101) + (98)(102) + ... + (1)(199), then the slope of the line passing through (α, β) and origin is:
We need to evaluate the sum:
Σ (100 - r) (100 + r) for r from 0 to 99.
Σ (100² - r²) for r from 0 to 99
= Σ 100² - Σ r² for r from 0 to 99
= 100 * 100² - [99 (99+1) (2*99+1)]/6
= 100³ - [99 * 100 * 199]/6
= 100³ - (1650 * 199)
Comparing this with (100)³ – 199β, we get:
β = 1650
If we consider a comparison fo
