Question

the difference between the square of the two consecutive number is 31 find the number

Answer 1

x,x+1
x²-(x+1)²=31
x²-(x²+1+2x)=31
x²-x²-1-2x=31
-1-2x=31
-2x=32
x=-16
x+1=-16+1=-15

Answer 2

This will be like..


=(a+1)²- (a)²=31

=a²+2a+1-a²=31

=2a+1=31

Now by solving this

=2a=31-1

=2a=30

=a=30/2=15

,The numbers are

a=15

a+1=15+1=16


That is the answer my friend
