Given three consecutive even natural numbers, which have the product of last two numbers is 80 greater than the product of first two numbers.
Find the largest number.
(x + 1)(x + 2) - x(x + 1) = 80
(x + 1)(x + 2 - x) = 80
(x + 1)2 = 80
x + 1 = 40
=> x = 39
=> x + 2 = 39 + 2 = 41
Vậy số lớn nhất là 41.

Đề bài : cho 3 số tự nhiên liên tiếp. Tích 2 số đầu cuối lớn hơn tích 2 số đầu là 80.
Gọi 3 số tự nhiên liên tiếp là a (a + 1) (a + 2).
Ta có (a + 1)(a + 2) = a(a + 1) + 80
=> (a + 1)(a + 2) - a(a + 1) - 80 = 0
=> a2 + 3a + 2 - a2 - a - 80 =0
=> 2a - 80 = 0 => a = 40
Vậy số lớn nhất là a + 2= 40 +2 =42
