Answer:

The answer is 24.

Step-by-step explanation:

Follow PEMDAS (parenthesis, exponents, multiplication, division, addition, subtraction).

Multiplication and Division can be on the same step from left to right, the same applies to Addition and Subtraction.

Original: 7 + 3² + (12 - 8) ÷ 2 x 4

Parenthesis: 7 + 3² + (4) ÷ 2 x 4

Exponents: 7 + 9 + 4 ÷ 2 x 4

Multiplication and Division from left to right: 7 + 9 + 2 x 4 = 7 + 9 + 8

Addition: 7 + 9 + 8 = 24

Hope this helps! :)

If 2k, 5k-1 and 6k+2 are the first 3 terms of an arithmetic sequence, find k and the 8th term.

Simora [160]

Consecutive terms in an arithmetic sequence differ by a constant $d$ . So

$5k-1=2k+d$
$6k+2=5k-1+d$
$\implies\begin{cases}3k-d=1\\k-d=-3\end{cases}\implies k=2,d=5$

Denote the $n$ -th term in the sequence by $a_n$ . Now that $a_1=2$ , we have

$a_n=a_{n-1}+5=a_{n-2}+2\cdot5=\cdots=a_1+(n-1)\cdot5$

which means

$a_8=2+(8-1)\cdot5=37$
