What is a formula for the nth term of the given sequence? 48, 72, 108

WITCHER [35]

Answer:

$a_n=48*1.5^{n-1}$

Step-by-step explanation:

Geometric Sequence

In geometric sequences, each term is found by multiplying (or dividing) the previous term by a fixed number, called the common ratio.

We are given the sequence:

48, 72, 108, ...

The common ratio is found by dividing the second term by the first term:

$r=\frac{72}{48}=1.5$

To ensure this is a geometric sequence, we use the ratio just calculated to find the third term a3=72*1.5=108.

Now we are sure this is a geometric sequence, we use the general term formula:

$a_n=a_1*r^{n-1}$

Where a1=48 and r=1.5

$\boxed{a_n=48*1.5^{n-1}}$

For example, to find the 5th term:

$a_5=48*1.5^{5-1}=48*1.5^{4}=243$

Write the following as an algebraic expression. Then simplify.

Ratling [72]

The sum of three even consecutive integers if the first integer is y will be 3y + 6.

First integer = y

Second integer = y + 2

Third integer = y + 4

Therefore, based on the expressions given above, the sum of the three integers will be:

= y + y +2 + y + 4

= 3y + 6

Therefore, the sum will be 3y + 6.
