Let $n$ be the number of integers $t$ such that $18 \leq t \leq 48$ and there exist positive integers $a$ and $b$ with $1 \leq a \leq 7$, $1 \leq b \leq 4$, and $t = 3a + 4b + 11$. Compute the $n$-th Fibonacci number, where $F_1 = 1$, $F_2 = 1$, and $F_k = F_{k-1} + F_{k-2}$ for $k \geq 3$.

comb_sum_binomial_mod_v1_1218484723_5613
A coding competition has a scoring system where each participant earns points of the form $3a + 2b$ with $1 \leq a \leq 3$, $1 \leq b \leq 4$. Let $T$ be the set of all distinct scores between $5$ and $17$ inclusive that can be achieved. Separately, a data pipeline computes $\sum_{k=23}^{193} \binom{204}{k}$ and takes ...
