The sum of five consecutive even numbers is 170. What are the five consecutive even numbers?
Let the middle one be 2n
Then the others are 2n-4 2n-2 2n + 2 2n + 4
Count again~
30,32,34,36,38
The sum of 5 consecutive even numbers is 170, the sum of 55 consecutive even numbers is 170, the sum of 5 consecutive even numbers is 170
The number in the middle is 170 △ 5 = 34,
Then the other numbers are 32.33.34.35.36
I wonder if you're asking for this

A and B drive from city a and city B. A travels a kilometer per hour, B travels 5 kilometers less than a, t if a = 60, t when two cars meet
(1) What is the distance between a and B?
(2) If a = 60, t = 2, what is the distance between a and B?
1) The distance between a and B is a * t + (a-5) * t = 2A * t-5tkm
2) If a = 60, t = 2, the distance between a and B is 2A * t-5t = 2 * 60 * 2-5 * 2 = 230 km
