Write the rule for the nth term of the following sequence.

denis-greek [22]

Answer:

$2^{n-3}$ is the nth term of the given sequence.

Step-by-step explanation:

The sequence given is

$\frac{1}{4},\frac{1}{2},1,2,4 .....$

We can clearly see that 1st term is $\frac{1}{4}$ and 2nd term is $\frac{1}{2}$

2nd term is obtained by multiplying the 1st term by 2.

2nd term is $\frac{1}{2}$ and 3rd term is 1.

3rd term is obtained by multiplying the 2nd term by 2.

3rd term is 1 and 4th term is 2.

4th term is obtained by multiplying the 3rd term by 2.

Clearly, the given series is a <em>Geometric Progression(GP)</em> with

First term, $a = \frac{1}{4}$

Common Ratio, $r = 2$

We know that $n^{th}$ term for a GP is:

$a_n = ar^{n-1}$

Putting values of <em>a</em> and <em>r</em>

$a_n = \dfrac{1}{4}2^{n-1}\\a_n = \dfrac{1}{2^{2} }2^{n-1}\\a_n = 2^{n-1-2}\\a_n = 2^{n-3}$

Hence, $2^{n-3}$ is the nth term of the given sequence.

10 mm<br>4 mm<br>u What is the volume of the cone to the nearest whole number?<br>

BaLLatris [955]

Answer:

V=167.5 cubic mm

Step-by-step explanation:

Volume of the Cone is given with the formula

$V=\frac{1}{3} \pi r^2h$

though we are not specified what is radius and which one is the height , we are assuming that ,

Height = 10 mm

Radius = 4 mm

Substituting these values in the formula we get

$V=\frac{1}{3} \pi 4^2 \times 10$

$V=\frac{1}{3} \pi 160$

$V=\frac{160 \times 3.14}{3}$

$V=\frac{160 \times 3.14}{3}$

$V=\frac{502.40}{3}$

$V=167.5$
