Answer 2

Answer:

$Average \: of \: first\: 10 \: odd \: natural \: numbers\\ =10$

Step-by-step explanation:

$We \: know\: that \\:</p><p>Sum \: of \: first \: n \: odd \: natural \: numbers = n^{2}$

$Average \: of \: first\: n \: odd \: natural \: numbers\\ = \frac{ sum\: of \: first \: n\: odd \: natural\:numbers }{n}\\=\frac{n^{2}}{n}\\=n$

$Average \: of \: first\: 10 \: odd \: natural \: numbers\\ = \frac{ sum\: of \: first \: 10\: odd \: natural\:numbers }{10}\\=\frac{10^{2}}{10}\\=10$

Therefore,

$Average \: of \: first\: 10 \: odd \: natural \: numbers\\ =10$
