Select all sequences that are geometric.
(A) 1.5, 6, 24, 96..
(B)2, 4, 6, 8, 10...
(C) 25,5, 1, 1/5,1/25...
(D) The circumference of a tree trunk
grows 2.5 inches each year:
8.25, 10.75, 13.25, 15.75...
(E) 1, - 1.5, 2.25, -3.375...

The answer is A, C, & E

Step-by-step explanation:

Sequence A has common ratio  

⇒ 4.

Sequence C has common ratio  

⇒ 0.2

Sequence E has common ratio  

⇒ -1.5

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
