The two consecutive integers are 25 and 26.

Divide $51$ by $2$ .

$51/2=25.5$

Decrease 25.5 to 25, and increase 25.5 to 26.

$25+26=51$

Let the first number be $x$

Then,the second number is $x+1$

So,
$x+(x+1)=51$

Remove brackets:

$rarrx+x+1=51$

$rarr2x+1=51$

$rarr2x=51-1$

$rarr2x=50$

$rarrx=50/2=25$

Then the second number is $x+1=25+1=26$

So,the two consecutive integers are $25 and 26$
