O to the power of 2 i think
we conclude that the sequence has 8 terms.
<h3>
How to get the number of terms in the sequence?</h3>
Here we have the geometric sequence:
2/81, 4/27, 8/9, ..., 6912
Notice that each term is equal to 6 times the previous term, such that:
2/81*6 = 4/27
4/27*6 = 8/9
Then the n-th term is equal to:

Where in this case:

Now we need to find the value of n such that:

If we apply the natural logarithm to both sides, then:

Then we conclude that the sequence has 8 terms.

Log(7x+1) - log(x-2) =1
log[(7x+1) / (x-2)] =1 or log[(7x+1) / (x-2)] =log10 (log10=1)
it means (7x+1) / (x-2) =10
Solving ===> x=7
IT IS IN triangle shapes hope it helps since some got 3 and the others got 4
