konstantin123 [22]

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:

$a_n = a_1*r^{n-1}$

Where in this case:

$a_1 = 2/81\\\\r = 6$

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

$(2/81)*6^{n-1} = 6912\\\\6^n = 6*6812*(81/2) = 1,679,616$

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

$n*ln(6) = ln(1,679,616)\\n = ln(1,679,616)/ln(6) = 8$

Then we conclude that the sequence has 8 terms.

$[Hello,BrainlyUser]$

Answer:

19.5

Step-by-step explanation:

Given that;

Recipe calls for 5.25 grams of chocolate

Question Ask;

If you have 102.375 grams of chocolate, how many batches,of the recipe can you make?

Note;

102.375 ÷ 5.25 = b

102.375 ÷ 5.25 = Solution
