Pearl writes down seven consecutive integers, and adds them up. The sum of the integers is equal to $214$ times the largest of the seven integers. What is the smallest integer that Pearl wrote down?

Alright, we set the largest of the 7 number to be x.

 

\(x-6+x-5+x-4+x-3+x-2+x-1+x = 214x\)

\(7x-21=214x\)

\(-21 = 207x\)

\(x = -21/207\)

that is not possible since they have to be integers.

hmmmm. Is this a trick question?

Ive googled this question. Electric Pavlov also answered this, and he got no answer as well. Check with your teacher, or the website, or whoever made this question.
