given that the sum of two consecutive natural number is 555, to get the number we proceed as follows. Natural numbers are positive integers, therefore we do not expect any negatives. Given that our numbers are consecutive, then it means they have a difference of 1.
Let one of the numbers be x
the second number will be x+1
the sum o the two numbers will be:
(x+1)+x=555
putting like terms together we get:
x+1+x=555
2x+1=555
2x=555-1
2x=554
x=554/2
x=277
hence the first number is 277
the second number is 277+1=278
