Question 846374: The sum of there natural number is 15. The second number is 1 more than the first number. The sum of the first and third number is eq
ual to twice the second number. Find all three numbers.
You can put this solution on YOUR website! 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
