Range = 2(n-1)

suppose, n = 5 even intergers >3
n = 10,12,14,16,18
range = 18-10=8
range = 2(n-1)=2(5-1) = 8

suppose, n = 4 even intergers >3
n = 10,12,14,16
range = 16-10=6
range = 2(n-1)=2(4-1) = 6

2(n-1)

n > 3....say we have 4 even cons +ve number....n+2, n+4, n+6, n+8 ==> 6
say we have 5 even cons +ve number...range = 8

So we have pattern of 6,8,10

2(n-1)

If the first number is a, the series is: a a+2 ... a+2(n-1)
So the range is a+2(n-1)-a=2(n-1)
