Numbers 1 to 100, Counting 1 to 100, 123, one two three

123 100  log(difference); Expected output: 2 abs; 1 ; 2 ; 0 The calculated value of the sum of is Given: The series of the first hundred natural numbers To Find: The sum of the numbers is to be found out

Make generalised formula for this 1+2+3+ till +99+100= The infinite series whose terms are the natural numbers 1 + 2 + 3 + 4 + ⋯ is a divergent series The nth partial sum of the series is the triangular number

There are two ways to approach this The first says “I know that 10 is one-tenth of 100 I will therefore divide 50 by 10 The answer is 5” This is fine Gauss realized then that his final total would be 50 = 5050 The sequence of numbers is arithmetic and when we are looking for the sum
