Check the picture below.
now, looking at the picture's scaling, from the lower-left-corner up to 20 is 5 squares, the rectangles you see in the picture are 40 units each, namely 10 squares. Every square is 4 units, it goes up 12 squares, namely 48 units, and goes to the right by 30 squares plus 4 more, 34 squares, that's 136 units.
well, if we were to make a triangle for the slope, check the picture, it'd look like that.
Why is the slope negative? well, because is going down from left to right.
For this case we must find the sum of the given series. For this we must expand the series for each value of k.
Different signs are subtracted and the sign of the major is placed, while equal signs of sum and the same sign is placed.
The value of the series is -16
ANswer:
-16
