Answer 1

Answer:4th: 729 6th: 6561

Step-by-step explanation: Sorry, I’m not 100% sure but I will try to help out: :)

So 2nd term is 81 and you want the 4th and 6th term.

Common ratio is 3

I approached it like this:

81x3=243 (3rd Term)

243x3=729 (4th Term)

729x3=2187 (5th Term)

2187x3=6561 (6th Term)

So if this isn’t the correct way the only other way I can think to approach this is

81+3=84(3rd Term)

84+3=87(4th Term)

87+3=90(5th Term)

90+3=93(6th Term)

Hope this helps
