If 2a = 10, what is 2a + 3?

First we need to find the value of a. To do this, divide both sides of the equation (2a = 10) by 2 to isolate the variable. 2a/2 = a, and 10/2 = 5. You are left with a = 5.
Now we need to plug in the value of a in the second expression. 2(5) + 3. Two times five equals 10, plus three is 13.
So, 2a + 3 = 13 when 2a = 10

32-20 = 12

14-2 = 12

 so the input is 12 more than the output

so 6+12 = 18

and

-10-12 = -22

If the second term of a geometric sequence of real numbers is -2 and the fifth term is 16 then what is the fourteenth term?
Agata [3.3K]
<h3>Given</h3>

A geometric sequence such that ...

a_2=-2\quad\text{and}\quad a_5=16

<h3>Find</h3>

a_{14}

<h3>Solution</h3>

We can use the ratio of the given terms to find the common ratio of the sequence, then use that to find the desired term from one of the given terms. We don't actually need the common ratio (-2). All we need is its cube (-8).

a_2=a_1r^{(2-1)}=a_1r^1\\a_5=a_1r^{(5-1)}=a_1r^4\\a_{14}=a_1r^{(14-1)}=a_1r^13=a_5r^9\\\\\dfrac{a_5}{a_2}=\dfrac{a_1r^4}{a_1r^1}=r^3=\dfrac{16}{-2}=-8\\\\r^9=\left(r^3\right)^3=(-8)^3=-512\\a_{14}=a_5(-512)\\\\a_{14}=-8192

anzhelika [568]

Answer:

Yes, it is effectively infinite

Step-by-step explanation:

An effectively infinite population refers to population from which it is possible to obtain a computable sub-population from it, and it is also effectively possible to construct another new sub-population from that same population that will not have elements already contained in the first sub-population.

The attributes of this kind of population is called effective infinity.

Database of recent graduates of any university possess this kind of attributes since it is possible to obtain another over 30,000 recent graduates from the database that will not have elements of the first 30,000.
