Question

The sum if 3 consecutive odd numbers is 39. What is the smallest number

Answer 1

odd number are numbers which when divided by 2 have a remainder

Let

the first number = a

the second number = a + 2

the third number = a + 2 + 2 = a + 4

a + a + 2 + a + 4 = 39

3a + 6 = 39

3a = 39 - 6

3a = 33

a = 33/3

a = 11

The smallest number is 11.
