<초급>(원래 있던 식들입니다.)

a+a^2+a^3+a^4+...+a^n=?

1+2+3+4+5+6+7+...+(n-1)+n=?

<중급>(그렇게 쉽지만은 않습니다.)

1+4+9+16+...+n^2=?

1+8+27+64+125+...+n^3=?

수열의 합이 x+자연수 인 수열이 존재하지 않음을 보이시오.

<고급>(제가 만든 식들입니다.)

1+16+81+...+n^4=?

1+32+243+...+n^5=?

1+64+729+...+n^6=?

초급과 중급은 단순문제라고 보셔도 되고요, 제가 6제곱까지 구한 김에 올린 겁니다. 고급은 셋중2개, 초급과 중급은 모두 답하면 되겟습니다.

이 문제 어떠셨나요?

글쎄요

      '초급'을 '중급'으로 바꿔 해석해 주세요. 오타입니다.
