Answer 2

let us assume that p=5, and q=3, as two odd prime numbers.
so
${p}^{2} - {q}^{2} = 25 - 9 \\ = 16$
composite numbers are those numbers which are having two or more prime factors ,unique or distinct.
so 16 is a composite number,because it can represented as 16 = 2X2X2X2
So if p and q are odd prime numbers,then
${p}^{2} - {q}^{2} is \: composite \: number$
