Find the sum of the first one hundred positive integers. see fig 6.26
nignag [31]
Here's a pattern to consider:
1+100=101
2+99=101
3+98=101
4+97=101
5+96=101
.....
This question relates to the discovery of Gauss, a mathematician. He found out that if you split 100 from 1-50 and 51-100, you could add them from each end to get a sum of 101. As there are 50 sets of addition, then the total is 50×101=5050
So, the sum of the first 100 positive integers is 5050.

Quick note
We can use a formula to find out the sum of an arithmetic series:
s =  \frac{n(n + 1)}{2}
Where s is the sum of the series and n is the number of terms in the series. It works for the above problem.

Can someone help me with this?

Answer:

\huge\purple{ x^2 +(y+2)^2 = 4}

Step-by-step explanation:

Circle is centred at (0, -2)

-> h = 0 & k = - 2

radius of the circle (r) = y-coordinate of the center = - 2

Equation of circle in standard form is given as:

(x-h)^2 +(y-k)^2 = r^2

Plugging the values of h, k and r in the above equation, we find:

(x-0)^2 +[y-(-2)]^2 = (-2)^2

\implies\huge\orange{ x^2 +(y+2)^2 = 4}

This is the required equation of circle.
