Question 12

There is a sequence of positive integers. The first term of the sequence is $1$, the second term is $2$, the third term is $3$ and the square of each number starting from the second one equals the sum of the two neighbouring terms. For example, for the second term we have that: $2^2=1+3$. What is the remainder when the $2023$rd term is divided by $11$?
