Odd numbers is 394.
The sum of the number is
Answers
.............................................................................................
STEP 1: Define the number:
Let one number be x
The other number is x + 2
.............................................................................................
STEP 2: Form the equation:
x² + (x + 2)² = 394
.............................................................................................
STEP 3: Solve x:
x² + x² + 4x + 4 = 394
2x² + 4x - 390 = 0
x²+ 2x - 195 = 0
(x - 13)(x + 15) = 0
x = 13 or x = - 15 (rejected, not natural number)
.............................................................................................
STEP 4: Find the numbers:
one number = x = 13
The other number = x + 2 = 13 + 2 = 15
.............................................................................................
STEP 5: Find the sum of the two numbers:
13 + 15 = 28
.............................................................................................
Answer: The sum of the 2 number is 28.

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 sum = 13 + 15 = 28
