Please help, I have no idea how to do it! The sequence $(a_n)$ is defined by $a_1 = \frac{1}{2}$ and
\[a_n = a_{n - 1}^2 + a_{n - 1}\]for $n \ge 2.$

Prove that
\[\frac{1}{a_1 + 1} + \frac{1}{a_2 + 1} + \dots + \frac{1}{a_n + 1} < 2\]for all $n \ge 1.$

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
