What is the 66th term in the following arithmetic sequence
-93, -85, -78, -71

d=  a2- a1

hence d= -85-(-93) = -85+93 = 8

a1= -93

d= 8

n=66

hence a66=a1+(n-1)d

a66= -93+ 65(8)

=-93+520

=427

66th term=427

pls mark as brainliest

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.
