Question

If the product of the two consecutive even integers is $35$. What is the second integer value?

• A. $-7$ or $-5$
• B. $7$ or $5$
• C. $-7$ or $5$
• D. $7$ or $-5$

Answer 1

The correct option is D $7$ or $-5$

Let the two consecutive even numbers be $x$ and $x+2$
Therefore, product of two consecutive number $=x(x+2)=35$
$x^2+2x=35$
On factoring we get the value of $x=5$ or $-7$
So, the second number will be $7$ or $-5$.
