Answer : The fifth term in the sequence is -2.

Step-by-step explanation :

As we are given that the expression to calculate the $n^{th}$ term.

The expression is as follows:

$a_n=2(-1)^n$

where,

n is the number of term

Given:

n = 5

Now putting the value of n in the above expression, we get:

$a_n=2(-1)^n$

$a_5=2(-1)^5$

$a_5=2\times (-1)$

$a_5=-2$

Therefore, the fifth term in the sequence is -2.

Answer:

The answer is the option

$72.31-17.92-15.33;\$39.06$

Step-by-step explanation:

Let

x-------> the balance at the beginning of the month

y------> total amount in deposits this month

we know that

$x+y=72.31$ -----> equation A

$y=17.92+15.33$ ------> equation B

Substitute

equation B in equation A

$x+(17.92+15.33)=72.31$

$x=72.31-17.92-15.33$

$x=\$39.06$

Answer:

Option B

Step-by-step explanation:

In a triangle , sum of measure of any 2 sides is always greater than the measure of the third side. So

$5 + 12 > k$

$= > 17 > k$

Hence the measure of k is less than 17.

In the triangle , measure of the longest side is 12 cm. As we know that sum of measure of any 2 sides of triangle is greater than the measure of third side , the value of k should be more than 7cm because <u>if the value of k would be 7 , then 5 + 7 = 12 and the sum will get equal to the measure of longest side , hence such triangle wont exist.</u>
