The endpoints of one diameter of a circle are (-6, 2) and (14,8). What is the center of the
circle?

To find the midpoint (center) add the x values together and divide by 2 and then do the same with the y values:

-6 + 14 = 8/2 = 4

2+8 = 10/2 = 5

Midpoint/ Center of the circle = (4,5)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
