if the sum of three consecutive positive number is 315. What is the numbers?

Answer 1

a = first number

b = second number = a + 1

c = third number = b + 1 = a + 1 + 1 = a + 2

a + b + c = 315

a + a + 1 + a + a + 2 = 315

3 a + 3 = 315

Subtract 3 to both sides

3 a = 312

Divide both sides by 3

a = 104

b = a + 1 = 105 + 1 = 105

c = a + 2 = 104 + 2 = 106

104 + 105 + 106 = 315

Answer 2

x+(x+1)+(x+2) = 315
3x + 3 = 315
X = 104
x+1 = 105
x+2 = 106.
