Determine the first four terms of the sequence in which the nth term is

Licemer1 [7]

<u>Answer:</u>

The correct answer option is: $\frac{1}{3} ,\frac{1}{4} ,\frac{1}{5} ,\frac{1}{6}$ .

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

We know that the $nth$ term $a_n$ for an arithmetic sequence is given by:

$a_n=\frac{(n+1)!}{(n+2)!}$

where $n$ is the number of the position of the term.

We are supposed to find the first four terms of the sequence so we will substitute the values of $n$ from 1 to 4 in the given formula to get:

1st term:

$a_1=\frac{(1+1)!}{(1+2)!}=\frac{1}{3}$

2nd term:

$a_2=\frac{(2+1)!}{(2+2)!}=\frac{1}{4}$

3rd term:

$a_3=\frac{(3+1)!}{(3+2)!}=\frac{1}{5}$

4th term:

$a_4=\frac{(4+1)!}{(4+2)!}=\frac{1}{6}$

How to write 2.31818 as a mixed fraction

Elenna [48]

Answer:

$2\frac{15909}{5000}$

Step-by-step explanation:

To make $2.31818$ into a fraction, you must first move it to the numerator and make 1 the denominator.

$\frac{2.31818}{1}$

And then you multiply it by $10,000$ or you can say $10^5$

$\frac{2.31818}{1}*\frac{100000}{100000}$

After you multiply you divide the numerator and denominator by 2.

$\frac{231818/2}{100000/2}$

And now this equals:

$2\frac{15909}{5000}$

Hope this helps!
