## Which two numbers have a sum of 15 and product of 36?

1 Answer.

The numbers are 3 and 12 ..

## What is the formula of sum of n terms?

Sum of N Terms Formula It is equal to n divided by 2 times the sum of twice the first term – ‘a’ and the product of the difference between second and first term-‘d’ also known as common difference, and (n-1), where n is numbers of terms to be added.

## What is the formula for sum of geometric series?

To find the sum of a finite geometric series, use the formula, Sn=a1(1−rn)1−r,r≠1 , where n is the number of terms, a1 is the first term and r is the common ratio .

## What is the sum of a number?

The result of adding two or more numbers. Example: 9 is the sum of 2, 4 and 3. (because 2 + 4 + 3 = 9).

## What 4 numbers add up to 15?

The possible number whose combination would result in sum of 15 are: 69, 78, 87, 96. So, there are only 4 combinations which would result in 15.

## What is the sum of meaning?

1 : an amount of (money) I paid the sum of $500. 2 : the result of (adding two or more numbers together) The sum of 5 and 7 is 12.

## What 4 numbers add up to 28?

## What is a sum of a series?

The sum of the terms of a sequence is called a series . If a sequence is arithmetic or geometric there are formulas to find the sum of the first n terms, denoted Sn , without actually adding all of the terms.

## What two numbers have a sum of 5 and have a product of 4?

Question: What is the pair of numbers with a sum of 5 and a product of 4? Answer: The two numbers that solve this problem are 1 and 4.

## How do you find the sum of numbers?

To do this, add the two numbers, and divide by 2. Multiply the average by the number of terms in the series. This will give you the sum of the arithmetic sequence. So, the sum of the sequence 10, 15, 20, 25, 30 is 100.

## What numbers can you add to get 15?

15 = 1 x 15 or 3 x 5. Factors of 15: 1, 3, 5, 15. Prime factorization: 15 = 3 x 5.

## What 4 numbers add up to 13?

1. Add: 9 + 4 = ? The sum of 9 + 4 is 13.

## What is the sum of 4?
