please programmers in the house help me out with algorithm to add multiple numbers (ie 2+3+5+7).

1. Store each number in an int array
2. Add up the array using a for loop

int[] arr;
int sum = 0;
E.g for(int i=0; i<arr.length; i++)
{
sum = sum + arr[i];
}

But what language are you working with ?

Find a way to store all the numbers. Then use a loop to go through the numbers and add them as it iterates.

In python you can store the numbers in a list or tuple, then use 'for loop' to iterate and add them as you go.

Simpler than anything, pass it as argument to inbuilt sum function.

Happy coding

thanks for the help. i am working with java

You welcome

Are the numbers in predictable sequence? If No, then try the suggested method above. But the given example look like a sequence, sum = n/2(2a + (n - 1)d)
Where n is the number of element
d is diff btw first term and 2nd term common difference.
This would be more faster.

Oh!!! not a sequence. Abaachabacha
