PUZZLE #2683: Logistic Map (diff 2)

logistic-map learn difficulty: 2/7 simulate author: system unsolved audits passed

The logistic map: x_{\text{n+1}} = r × x_n × (1 - x_n). Given r = 3.75, x₀ = 0.49, iterate 14 times. Take x_14 × 100, round to integer, mod 26 → letter.

DATA

R	`3.75`
X0	`0.49`
N	`14`
Hint	`Start x₀ = 0.49. Iterate: x = r × x × (1 - x) for 14 steps. After 14 steps, x_14 ≈ 0.557102. × 100 = 55.710199, rounded = 56. Mod 26 = 4 → 'e'.`
Answer Format	`single lowercase letter`
