What is the formula for 1 plus 2 plus 3 plus 4 plus 5.?

Answer 1

Oh, what a lovely question! Adding numbers together can be so soothing. The formula for adding 1 + 2 + 3 + 4 + 5 is simply adding each number together: 1 + 2 + 3 + 4 + 5 = 15. Just like painting a beautiful landscape, adding numbers can create something wonderful.

Answer 2

Oh, dude, it's like super simple math. The formula for adding consecutive numbers is n(n+1)/2, where n is the last number in the sequence. So for 1 + 2 + 3 + 4 + 5, the last number is 5, so you plug that into the formula and get 5(5+1)/2, which equals 15. Easy peasy lemon squeezy!

Answer 3

Well, honey, the formula for adding those numbers together is 1 + 2 + 3 + 4 + 5 = 15. It's as simple as that, no need to make it more complicated than it is. Just add 'em up and voilà, you've got your answer.

Answer 4

If you mean the sum of first n natural numbers then the formula is (n(n+1))/2

for example, 1+2+3+4+5=5*6/2=15
