The sum of three natural number is 15.
a + b + c = 15
The second number is 1 more than the first number.
b = a + 1
The sum of the first and third number is equal to twice the second number.
a + c = 2b
:
In the first equation replace a + c with 2b
2b + b = 15
b = 15/3
b = 5
then
b = a + 1
a = 4
I'll let you find c

Find all three numbers.
