Answer 2

A fraction is reducible if there is some factor (not 1) that both numbers share. The factors of 91 are 1, 7, 13, and 91. None of these (except 1) are factors of 816 so it is irreducible.

Answer 3

Can you check my arithmetic in this geometric sequence? What is the sum of the first 5 terms of a geometric series with a1=6 and r+1/3. @vinnv226

Answer 4

no

Answer 5

What is the sum of the first 5 terms of a geometric series with a1=6 and r=1/3. @mathstudent2000

Answer 6

242/27

Answer 7

Honestly it's been a while since I've looked at sequences and series. Five terms isn't a lot though, so i would just write them out. Start with 6, and each successive term is one third of the previous one. Then just add them together once you get 5 terms.
