Answer: $\bold{a_1=\dfrac{1}{2}\qquad a_n=\bigg(\dfrac{4}{3}\bigg)a_{n-1}}$

<u>Step-by-step explanation:</u>

The explicit rule for a geometric sequence is: $a_n=a_1(r)^{n-1}\quad \text{where}\ a_1\ \text{is the first term and r is the common ratio}$

$\text{From the explicit rule provided:}\ a_n=\dfrac{1}{2}\bigg(\dfrac{4}{3}\bigg)^{n-1}}\\ \text{we know that}\ a_1=\dfrac{1}{2}\ \text{and r =} \dfrac{4}{3}$

$\text{The recursive rule for a geometric sequence is:}\ a_n = (r)a_{n-1} \\\\\text{So, the recursive rule is:}\ a_n=\bigg(\dfrac{4}{3}\bigg)a_{n-1}$

Find the three consecutive even integers such that one half of their sum is between 15 and 21. set up and solve a compound inequ

Kay [80]

The even integers are 10,12 and 14.

Concept: An integer is colloquially defined as a number that can be written without a fractional component. For example, 21, 4, 0, and −2048 are integers, while 9.75, 5+1/2, and √2 are not.

Let x,x+2,x+4 be the least, middle and greatest integer respectively.

According to the question,

15< x+x+2+x+4< 21

(3x+6)/2> 15 and (3x+6)/2< 21

30< 3x+6 3x+6> 42

24<3x 3x<36

8<x x>12

x=10

x+2=12

x+4=14

Hence, The even integers are 10,12 and 14.
