## Grade 7 MTAP 2015 Questions with Solutions Part 4

This is the fourth part of the Metrobank-MTAP Math Challenge Questions for Grade 7. In this post, we discuss the solutions to number 21-30. You can also read the solutions to 1-10, 11-20, and 21 – 30.

31.) If $n$ is a prime number not equal to 2, which of the following can be a prime: $n + 3$, $2^n - 1$, $n^2 + 1$.

Solution

All prime numbers not equal to 2 are odd. If $n$ is odd, then $n + 3$ and $n^2 + 1$ are both even, while $2^n - 1$ is odd. Therefore, only $2^n - 1$ can be a prime.

Answer: $2^n - 1$

32.) What must be added to the product of $2x - 1$ and $4x +5$ to obtain $4x^2 + 8x + 1$Continue reading
