Question

find the sum of first 200 natural number s​

Answer 1

Answer:

$\red {Sum \: of \: first \:200\: natural \: numbers}$

$\green {= 20100}$

Step-by-step explanation:

$\red {Sum \: of \: first \:n \: natural \: numbers}$

$\orange {= \frac{n(n+1)}{2}}$

$Here , n = 200$

$\red {Sum \: of \: first \:200\: natural \: numbers}$

$=\frac{200(200+1)}{2}\\= 100\times 201\\= 20100$

Therefore.,

$\red {Sum \: of \: first \:200\: natural \: numbers}$

$\green {= 20100}$
