Question

Solve this for me, please

Answer 1

The answer is : d (2,6,18,54,162)

the geometric sequence formula : a+ ar^1 +ar^2+ar^3+...........

where r= common ratio

the sequence is : 2,6,18,54,162

r = An/An-1 ( as per the formula)

r = 162/54 = 3

r = 54/18 = 3

lly common ratio =3

in the given options the only option d satisfies all the conditions of the geometric sequence

verification :

a= 2

ar^1 = 2*3 = 6

ar^2 = 2*9 =18

ar^3 = 2*27 = 54

ar^4 = 2*81 = 162

hence verified the sequence is 2,6,18,54,162

Answer 2

the answer should be B

Explanation:

using advanced methods of taking tests and doing multiple choice I've come to realization the answer is never A and if the answer is a then you are wrong. the teachers always think that you're going to guess C so the answer will never actually be C. the last answer is D and the teacher will never make the answer D because who actually uses D. therefore using this advanced process of elimination we have cut the terms that answer should be and most definitely will be totally 100% be B.
