Can anyone help with this please

Which of the following is most likely the next step in the series? a3z, b6y, c9x, d12w, е15v, f18u

In the geometric progression –3, 12, −48… what term is 3,072?

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′.
