The first term of a geometric sequence is 32, and the 5th term of the sequence is 818 .

sammy [17]

Answer:

$32,24,18,\frac{27}{2} ,\frac{81}{8}$

Step-by-step explanation:

Let x, y , and z be the numbers.

Then the geometric sequence is $32,x,y,z,\frac{81}{8}$

Recall that term of a geometric sequence are generally in the form:

$a,ar,ar^2,ar^3,ar^4$

This implies that:

a=32 and $ar^4=\frac{81}{8}$

Substitute a=32 and solve for r.

$32r^3=\frac{81}{8}$

$r^4=\frac{81}{256}$

Take the fourth root to get:

$r=\sqrt[4]{\frac{81}{256} }$

$r=\frac{3}{4}$

Therefore $x=32*\frac{3}{4} =24$

$y=24*\frac{3}{4} =18$

$z=18*\frac{3}{4} =\frac{27}{2}$

Which sentence uses present tense?

mamaluj [8]

As for this problem, the answer would most probably be and most likely be C. The piles of bones foreshadow Fortunato's fate.

In the first option, symbolizing wasn't used in present tense but a simple mixing of present and past tense. The more appropriate form of the sentence would be "The catacombs was dark and cold which symbolized death." This would be a lot more understandable and it will not create confusion to the readers because of the inconsistency of the usage of tenses. The second option and the last option would be both in past tenses. The correct one is used in plural present form.
