Question

The sum of Number of two consecutive odd number is 394.find the number

Answer 1

Answer:

consecutive odd numbers = x, x + 2

x + x + 2 = 394

2x + 2 = 394

2x = 394-2 = 392

x = 392/2 = 196

numbers will be 196 & 198

Answer 2

Answer:

Let the numbers be x and (x + 2)

• According to the Question :

⇒ x² + (x + 2)² = 394

⇒ x² + x² + 4x + 4 = 394

⇒ 2x² + 4x - 390 = 0

⇒ x² + 2x - 195 = 0

⇒ x² + 15x - 13x - 195 = 0

⇒ (x + 15)(x - 13) = 0

⇒ x = 13

• Required Numbers :

◗ x = 13

◗ (x + 2) = 13 + 2 = 15
