Question

1 से 29 तक की संख्याओं का औसत क्या होगा​

Answer 1

Step-by-step explanation:

Translated Question:-

Calculate the average of Numbers from 1 to 29.

Answer :-

We know that

$\boxed{\sf Average=\dfrac{Sum\:of\:terms}{Number\;of\:terms}}$

$\boxed{S_n=\dfrac{n(n+1)}{2}}$

$\\ \sf{:}\rightarrowtail S_n=\dfrac{29(29+1)}{2}$

$\\ \sf{:}\rightarrowtail S_n=\dfrac{29(30)}{2}$

$\\ \sf{:}\rightarrowtail S_n=\dfrac{870}{2}$

$\\ \sf{:}\rightarrowtail S_n=435$

$\\ \sf{:}\rightarrowtail Average=\dfrac{S_n}{n}$

$\\ \sf{:}\rightarrowtail Average=\dfrac{435}{29}$

$\\ \bf{:}\rightarrowtail Average=15$
