Answer 1

Answer:

the question is wrong please tell the correct question because even consecutive numbers are 0,2,4,6 and ther sum is 12

Answer 2

Answer:

Four consecutive even numbers can be written as n, n+2, n+4 and n+6. Their sum is 4n + 12. You say that 4n+12 = 7(n+6). Solving this, we have 4n+12 = 7n+ 42, or 3n = -30, or n=-10. So the four numbers are -10, -8, -6 and -4. Checking, the sum of these is -28, which is 7 times the greatest integer (-4).
