등차수열 Sn = n(a+ℓ)/2 = n{2a+(n-1)d}/2 등차수열 an+1 = a + nd / an = a + (n-1)d 등차중앙 2b = a+c 등비수열 Sn = a(1-rⁿ)/(1-r) = a(rⁿ-1)/(r-1) 등비수열 an+1 = arⁿ 등비중앙 b² = ac 복리 Sn = a(1+r){(1+rⁿ)-1}/r 복리의 an = a(1+r)ⁿ 제곱 Sn = n(n+1)(2n+1)/6 세제곱 Sn = {n(n+1)/2}²

아무리 긴 문장이어도 "It is ~~~ that ~~~." 의 형태라면, ~~~을 강조하기 위한 형태이므로 이 부분만 해석해도 말이 될 것이다. It is when we share our findings with people with other areas of expertise or perspectives, or seek feedback about our concept from someone in a different field, or try out our idea with potential users, that suddenly the real potential starts to emerge.
