In a particular sequence, each term is 3 times the last. the sequence begins with 2,6,18. write the next four terms of the sequence

54, 162, 486, 1458

Step-by-step explanation:

To obtain the next term in the sequence multiply the previous term by 3

18 × 3 = 54

54 × 3 = 162

162 × 3 = 486

486 × 3 = 1458

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
