Problema Solution

The sum of three consecutive odd integers is 189. What are the integers?

Answer provided by our tutors

61, 63, 65


solving using algebra

x = first number

x+2 = second number

x+4 = third number


x + (x+2) + (x+4) = 189


3x + 6 = 189


3x = 183


x = 61


x+ 2 = 63


x + 4 = 65


Alternative method for solving the sum of consecutive numbers


divide the sum by the number of numbers you are adding together


this is the middle number


189/3 = 63


since this is the middle number the other two consecutive odd numbers are 61 and 65
