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
