Answer:
The sum of the first 51 terms of the sequence is 6018
Step-by-step explanation:
AP: −282,−266,−250,−234,...
First term = a = -282
Common difference = d =
Common difference = d = -266-(-282)=-250-(-266)=16
Formula of sum of first n terms =
Substitute n = 51
So,
Hence the sum of the first 51 terms of the sequence is 6018
Answer:
slope is undefined
Step-by-step explanation:
calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (6, 4 ) and (x₂, y₂ ) = (6, - 2 )
m = =
division by zero is undefined, therefore the slope of the vertical line is undefined.
