10 10 x 10 10 x 10x10 x10
Sever21 [200]
The answer is 10,000,000 because u have to do 10x10x10x10x10x10x10


So basically I did the most easiest way possible with is multiply 1 and 1 and then add the zero and I got 10 so if u add the zeros up 6 more times then we get 10 million or 10,000,000.

Consider the following sequence of numbers 3, -9, 27, -81, ….
lesya [120]

<u>QUESTION 1</u>

The given sequence is 3,-9,27,-81,....

The first term of the sequence is a_1=3

The second term is a_2=-9


The common ratio can be found using any two consecutive terms of the sequence.

Thus, the common ratio is given by r=\frac{a_n}{a_{n-1}}.


This implies that,

r=\frac{-9}{3}

This simplifies to,

r=-3


The correct answer is C


<u>QUESTION 2</u>

The sum of the first n terms of a geometric sequence is given by;

S_n=\frac{a_1(r^n-1)}{r-1}.

Since we are looking for the first five terms, we substitute n=5, a_1=3 and r=-3 into the formula to obtain,

S_5=\frac{3((-3)^5-1)}{-3-1}


This will evaluate to give us;

S_5=\frac{3(-243-1)}{-3-1}


S_5=\frac{3(-244)}{-4}


\Rightarrow S_5=3\times 61


\Rightarrow S_5=183


The correct answer is A
