Question

The largest number of the three consecutive number is $x+1$ then the smallest number is

• A. $x+2$
• B. $x+1$
• C. $x$
• D. $x-1$

Answer 1

The correct option is D $x-1$

Largest of consecutive numbers is $(x+1)$.

We know that consecutive numbers differ by 1.

So consecutive number before $(x+1)$ is $(x+1)-1$ i.e $x$

So the 1st number of three consecutive numbers will be $(x-1)$.

We know that $(x-1)<x<(x+1)$

So smallest of all consecutive numbers is $x-1$
