Find the common denominator of 6 and 4.
6: 6, 12...
4: 8, 12...

We can use 12 for this example.

5/6 to ?/12.
12 / 6 = 2, therefore do 5 x 2.
5 x 2 = 10. 10/12.

1/4 to ?/12.
12 / 4 = 3, therefore do 3 x 1.
3 x 1 = 3. 3/12.

13/12. 1 1/12.

I believe you ran out of space or didn't put answer D. I researched this question and concluded that the other choice is 1 and 1/12.

The answer is 1 and 1/12.

-1,-4,-7,-10 write an equation to find the nth term of each sequence. Then find a24

Natasha_Volkova [10]

Answer:

$\boxed {a_{24} = - 70}$

Step-by-step explanation:

According to the following pattern sequence ( $-1, -4, -7, -10$ ), it is <u>Arithmetic Sequence</u>, because every negative number is subtracted by $3$ . So, to find the <u>24th term</u>, you need to use the <u>Arithmetic Sequence Formula</u> and solve to find the 24th term:

$a_{n} = a_{1} + (n - 1) d$

$a_{n}$ : nth term in the sequence

$a_{1}$ : 1st term

$n$ : term position

$d$ : Common difference

-Apply to the formula:

$a_{24} = -1 - 3 (24 - 1)$

$a_{n} = a_{24}$

$a_{1} = -1$

$n = 24$

$d = -3$

-Solve:

$a_{24} = -1 - 3 (24 - 1)$

$a_{24} = -1 - 3 (23)$

$a_{24} = -1 - 69$

$\boxed {a_{24} = - 70}$

Therefore, the 24th term is $-70$ .
