Note that there are 50 odd numbers from 1 to 100. i.e., n = 50. Therefore, the sum of odd numbers from 1 to 100 = n2 = 502 = 2500. What is the Sum of First n Odd Natural Numbers? The sum of first n odd natural numbers can be represented as 1 + 3 + 5 + ... + (2n...
This note generalizes the formula for the triangular number of the sum and product of two natural numbers to similar results for the triangular number of the sum and product of r natural numbers. The formula is applied to derive formula for the sum of an odd and an even number of ...
In this narrative, I will detail how, starting from basic experiences as an infant, I independently observed, experimented, and logically deduced what is known asGauss's Formulafor the sum of the first nnn natural numbers: S=1+2+3+⋯+n=n(n+1)2S = 1 + 2 + 3 + \dots + n = \...

The ratio of interest and principal for one year is called the annual interest rate. The ratio of the principal and interest of the month is called a monthly interest rate. 48, natural numbers used to indicate the number of integer objects, called natural numbers. 0 is the natural number....
Example: Find the geometric mean of 4 and 3 ? \(\begin{array}{l}Geometric Mean = \sqrt{4 \times 3} = 2 \sqrt{3} = 3.46\end{array} \) Harmonic Mean The harmonic mean is used to average ratios. For two numbers x and y, theharmonic meanis 2xy(x+y). For, three numbers x,...
Round then sum values with one formulaTo round then sum values with one step, you just need an array formula. Select a cell you want to put the final result out, and type this formula =SUM(ROUND(B2:B5,0)) into it, then press Shift + Ctrl + Enter keys to get the result. See ...
