Answer:
The sum of arithmetic series is - 2119 .
Step-by-step explanation:
Given as :
The first term of series = a = - 94
The 26th term of series =
= - 69
The number of term = n = 26
Now, Let The sum of arithmetic series = ![s__n](https://tex.z-dn.net/?f=s__n)
So,
=
× (First term + Last term)
Or,
=
× (a +
)
or,
= 13 × ( - 94 - 69 )
or,
= 13 × ( - 163 )
or,
= - 2119
or, the sum of 26 arithmetic series =
= - 2119
Hence The sum of arithmetic series is - 2119 . Answer
from the provided focus point and directrix, we can see that the focus point is above the directrix, meaning is a vertical parabola and is opening upwards, thus the squared variable will be the "x".
keeping in mind the vertex is half-way between these two fellows, Check the picture below.
