Ageometric sequence is defined by the explicit formula an = 5(-4)n-1. what is the recursive formula for the nth term of this sequence?

a. an = -5an-1
b. an+1 = 4an
c. an+1 = 5an
d. an = -4an-1

Type the correct answer in each box. spell all words correctly. a sequence of transformations maps ∆abc onto ∆a″b″c″. the type of transformation that maps ∆abc onto ∆a′b′c′ is a . when ∆a′b′c′ is reflected across the line x = -2 to form ∆a″b″c″, vertex of ∆a″b″c″ will have the same coordinates as b′.

Answer! if you don’t mind, can you explain

Ab and bc are tangent to circle d. find x is ab = 3x + 8 and bc = 26. find x
