Question

Product of two consecutive even number is double of greater number

Answer 1

Answer:

Step-by-step explanation:

It is simple. Find out the square root of the given number. Since the product is of consecutive numbers, you have to find the square root of the number. Once you get the square root, you find the next consecutive even number.

here, the square root of 12768 is 112.995575.

Since the square root is greater than 112 here, the next consecutive even numbers are 114, 116…

the number required is closest to 112. multiply the last digits of both numbers and verify it with the last digit of the given number 12768.

Here, 112 x 114 = 12768

Therefore it is 114
