Answer:

3n -4

Step-by-step explanation:

We are adding 3 each time

-1+3 =2

2+3 = 5

The formula for an arithmetic sequence is

an = a1+d(n-1) where a1 is the first term and d is the common difference

an = -1+3(n-1)

= -1 +3n -3

= 3n -4

When solving negative one over eight (x + 35) = −7, what is the correct sequence of operations?

Fantom [35]

The answer is <span>Multiply each side by −8, subtract 35 from each side

</span> $- \frac{1}{8}(x+35)=-7$
<span>
Multiply each side by -8:
</span> $(-8)(- \frac{1}{8})(x+35)=(-8)(-7) \\ \\ 
1(x + 35) = 56 \\ 
x + 35 = 56$
<span>
Subtract 35 from each side:
</span> $x + 35 -35 = 56-35 \\ \\ 
x + 0 =21 \\ \\ 
x = 21$ <span>
</span>
