Question

numbers.
4. The sum of three consecutive even numbers is 120. What are the numbers​

Answer 1

Answer:

2n + (2n + 2) + (2n + 4) = 120

2(19) + (2(19) + 2) + (2(19) + 4) = 120

38 + (38 + 2) + (38 + 4) = 120

38 + (40) + (42) = 120

38 + 40 + 42 = 120

78 + 42 = 120

120 = 120

Therefore, 2n = 38 is the smallest of three consecutive even numbers whose sum is 120
