Question

Let a and b be two consecutive even natural numbers and let a²-b²=1236.Calculate the largest number of the two numbers

​

Answer 1

Larger number is 618.5

Explanation:

=> a = b + 1

=> a - b = 1

Now,

=> a² - b² = 1236

=> (a + b)(a - b) = 1236

=> (a + b)(1) = 1236

=> (a + b) = 1236

Now,

a + b = 1236

=> b + 1 + b = 1236

=> 2b = 1235

=> b = 617.5

=> a = 618.5
