Answer»

LET suppose first no as x,

So the series is LIKE,

⇒ x, x + 1, x + 2, ....., x + 5

⇒ Sum of six NUMBER = 483

⇒ x + x + 1 + x + 2 + x + 3 + x + 4+ x + 5 = 483

⇒ 6x + 15 = 483

$(\Rightarrow x = 78)$

⇒ Fourth no. = x + 3 = 81

⇒ Sixth no. = x + 5 = 83

⇒ Sum = 81 + 83 = 164

∴ Sum of fourth and sixth number is 164
