There is a jar of jellybeans on Mr. Wallace’s Desk. He asked some students to guess the number of jellybeans in the jar.

Annie guessed 206, Bert guessed 197, Estella guessed 212 and Feliciano guessed 221.

Mr. Wallace told the students “No guesses were correct, but one guess was off by 4 jellybeans, one was off by 13 jellybeans, one was off by 11 jellybeans, and one was off by 2 jellybeans. I will give you extra credit if you can figure out the number of jellybeans now.”

What is the correct number of jellybeans?
