Answer:
Heya user.........❤
Let the first term be a & common ratio be r.
sum to infinity terms = a/(1-r)
Hence,
2/(1-r) = 6
=> 2 = 6-6r
=> 6r =4
=> r = 4/6
=> r = 2/3
So, the common ratio is 2/3.

Step-by-step explanation:
Let the first term be a common ratio be R.
Sum to infinity terms= a/(1-R)
Hence,
2/(1-R)=6
= •°• 2=6-6R
= 6R=4
= R=4/6
R= 2/3
So, the simple ratio is 2/3.
