    judging from your past questions...this has something to do with arithmetic/geometric sequence?

    here's another one... \[12C10 \implies \frac{12!}{10!(12-10)!} \implies \frac{12!}{10!2!} \implies \frac{12 \times 11 \times \cancel{10!}}{\cancel{10!} 2!} \implies \frac{12 \times 11}{2 \times 1}\] does that help?
