उत्तर
Let us assume three consecutive even numbers of series to be x, x + 2 and x + 4
So, The sum of consecutive even numbers = x + x + 2 + x + 4
48 = 3x + 6
– 3x = 6 – 48
– 3x = – 42
x = 14
Therefore, Three consecutive even numbers = x, x + 2 and x + 4.
x + 2 = 14 + 2 = 16
x + 4 = 14 + 4 = 18,
Which is the biggest number in the series.
