Question

Find three consecutive integers such that their sum is $78$

Answer 1

Sum of three consecutive integers$=78$

Let first number$=x$

The second number$=x+1$

and third number$=x+2$

Then $x+x+1+x+2=78$

$\Rightarrow 3x+3=78$

$\Rightarrow 3x=78-3=75$

$\Rightarrow x=\frac{75}{3}=25$

$\therefore$first number$=x=25$

The second number$=x+1=25+1=26$

and third number$=x+2=25+2=27$

Then the three required numbers are $25,16,27$
