Question

The sum of two consecutive numbers is 71. Frame an equation for this statement.

• A. $2x+1=71$
• B. $x+(x+2)=71$
• C. $x+x=71$
• D. none of these

Answer 1

The correct option is A

$2x+1=71$

Let the first number be $x$
Now, it is said that the two numbers are consecutive, so we add $1$ to $x$,

$\therefore$ the other number = $x+1$.
Hence, the equation is $x+(x+1)=71$
$\Rightarrow$ $2x+1=71$
