8.94427191
Step-by-step explanation:
We want to find the length ( or distance) between the two points
d = sqrt( (x2-x1)^2 + (y2-y1)^2)
= sqrt( (8-0)^2 + (1 - -3)^2)
= sqrt( (8)^2 + (4^2)
= sqrt( 64+16)
sqrt( 80)
sqrt(16) sqrt(5)
4 sqrt(5)
8.94427191
The first term is 2(1) - 9 = -7
the common difference is 2
there are (18 - 1) + 1 = 18 terms in this series
the 18th term is -7 + 2(18-1) = 27
the sum is
sn = 18/2(-7 + 27) = 180
