Which of the following are geometric sequences? A. 3, 6, 9, 12 ,15, 18 B. 5, 10, 20, 40, 80, 160 C. 10, 5, 2.5, 1.25, 0.625, 0.3125 D. 1, 3, 9, 27, 81 ***Choose ALL that apply!!!! so i have this so far... A. (+3) B. (x2) C. (x 1/2) D. (x3) so idk which are geometric sequences??
are geometric sequences with addition? or multiplication?? idk :/
the ones where you multiply each term by the same number to get the next term is a geometric sequence
so my answers are B,C,D ??? or is C even an answer?? cuz its multiplied by .5?
all of them looks like geometric sequences to me
which is an arithmetic sequence
right sorry not A my bad
okay great!! so B,C,D are my answerS/??
