 # Quick Answer: What Are Three Consecutive Numbers Have A Sum Of 126?

## What three consecutive numbers have a sum of 123?

What three consecutive integers have a sum of 123.

Which means that the first number is 40, the second number is 40 + 1 and the third number is 40 + 2.

Therefore, three consecutive integers that add up to 123 are 40, 41, and 42.

We know our answer is correct because 40 + 41 + 42 equals 123 as displayed above..

## What is the sum of consecutive numbers?

By using Carl Gauss’s clever formula, (n / 2)(first number + last number) = sum, where n is the number of integers, we learned how to add consecutive numbers quickly. We now know that the sum of the pairs in consecutive numbers starting with the first and last numbers is equal.

## IS 125 a perfect square?

Is 125 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 125 is about 11.180.

## What are factors of 90?

Therefore, the pair factors of 90 are (1, 90), (2, 45), (3, 30), (5, 18), (6, 15) and (9, 10).

## What is the sum of 2 consecutive numbers?

The sum of any two consecutive numbers is always odd. Example, 4 + 5 = 9; –8 + (–7) = –15.

## What is the sum of consecutive odd numbers?

Sum of first odd number = 1. Sum of first two odd numbers = 1 + 3 = 4 (4 = 2 x 2). Sum of first three odd numbers = 1 + 3 + 5 = 9 (9 = 3 x 3). Sum of first four odd numbers = 1 + 3 + 5 + 7 = 16 (16 = 4 x 4).

## How do you find three consecutive numbers whose sum is 126?

If the three numbers are consecutive then call the first number x. The number after x will be (x + 1) and the number after that will be (x + 2). To find the sum then add the three numbers up. So the three numbers are 41, 42 and 43.

## What is the sum of 3 consecutive numbers?

Correct answer: Explanation: Three consecutive even integers can be represented by x, x+2, x+4. The sum is 3x+6, which is equal to 108.

## What are all the factors of 126?

126 and Level 5. 126 is a composite number. 126 = 1 x 126, 2 x 63, 3 x 42, 6 x 21, 7 x 18, or 9 x 14. Factors of 126: 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126.

## What are the integers of 87?

What three consecutive integers have a sum of 87? Which means that the first number is 28, the second number is 28 + 1 and the third number is 28 + 2. Therefore, three consecutive integers that add up to 87 are 28, 29, and 30. We know our answer is correct because 28 + 29 + 30 equals 87 as displayed above.

## Is the number 6 a multiple of 3?

## What is the sum of 2 consecutive even number?

Hence the answer is 42. The coincidence is that the sum of those two numbers is half of the difference of their squares. But its universal for 2 consecutive even numbers and odd numbers.
