Question

to find the sum of the first 7 natural numbers, take n=7​

Answer 1

Answer:

$Sum\:of \: first \:7 \: natural\\numbere =28$

Step-by-step explanation:

$Sum \: of \: first \: n \\ natural\: numbers = \frac{n(n+1)}{2}$

$Here ,n=7\\</p><p>Sum\:of \: first \:7 \: natural\\numbere = \frac{7(7+1)}{2}\\=\frac{7\times 8}{2}\\=7\times 4\\=28$

Therefore,

$Sum\:of \: first \:7 \: natural\\numbere =28$
