Explanation: hope it helps
If the sum of two equal even numbers is 400, the numbers will be 200+200.
Therefore the largest possible consecutive even numbers which have a sum of 400 or less are 198 and 200 which have a sum of 398.
Any pair of consecutive numbers less than these will have a sum of less than 400.
