Answer:
1. 13 and 15 2. Take the two numbers as 2x and 2x + 2 and follow the same procedure as 1
Step-by-step explanation:
1.
Let 2x+1 be a odd number and 2x+3 is the next odd number.
Then, ATQ,
(2x+3)² - (2x+1)² = 56
⇒ (4x² + 12x + 9) - (4x² +4x +1) = 56
⇒ 12x - 4x + 9 - 1 = 56
⇒ 8x+8 = 56
⇒ x+1 = 56/8 = 7
⇒ x= 7-1 = 6
∴ the two consecutive odd numbers are 2x + 1 = 2 × 6 +1 =13 and 2x +3 = 2 × 6 +3 =15
2. take the two consecutive even numbers to be 2x and 2x +2 and follow the same procedure as 1.
