What is formula to find sum of n even numbers?
There is no formula that will sum n even numbers without further qualifications: for example, n even numbers in a sequence.
Is the sum of two even numbers even or odd?
The sum of two even numbers is always EVENYes.Proof:We can consider an even number as 2*n, and an odd number as 2*n+1.The sum of two even numbers would be 2*n+2*m=2*(n+m), an even number.
Why is the sum of four consecutive numbers always even?
If n is the first number, n + n + 1 + n + 2 + n + 3 will be the sum, which is 4n + 6. 4n is always even, and 6 is even. Therefore, the sum of four consecutive numbers is always even.
Write the algorithm and draw the flowchart to find Sum of N Prime number?
Ah, finding the sum of N prime numbers is a lovely challenge! You can create an algorithm by first defining a function to check if a number is prime, then loop through numbers starting from 2 and add the prime numbers to a running sum until you reach N prime numbers. For the flowchart, you can start with a start/end symbol, then use decision symbols to check if a number is prime, loop symbols to iterate through numbers, and a process symbol to calculate the sum. Remember to add symbols for input and output as well. Happy algorithm painting!
What is the formula to find out the sum of first n even numbers?
n*(n+1)
