The difference of squares of two consecutive odd numbers is 88. What is the product of the two numbers?
Given:
Difference of squares of two consecutive odd numbers = 88
Formula Used:
Solution:
Let the two consecutive odd numbers be x and x + 2.
= 88
= 88
4x + 4 = 88
4x = 84
x = 21
The first odd number is 21.
The consecutive odd number is 21 + 2 = 23.
Now, find their product.
Product = 21 × 23 = 483
Final Answer
So the correct answer is (d)
