Answer: b= -5 over 3

Step-by-step explanation:

create the equation 3b + 9 = 4

subtract 9 from each side to isolate the variable

we are left with 3b = -5

to further isolate the variable divide by 3

3b/3 = -5/3

3b divided by 3 is b, which is equal to -5 divided by 3; -5/3

b = -5/3 is your answer

Sorry, I only know 8, 9, and 10.

8. This can be anything, but my guess would be 40 - 20 = 20
9. 3, because 3 x 3 = 9.
10. 7, because 7 x 4 = 28.

Hope this helped!

Answer:

Step-by-step explanation:

Look at any 2 adjacent numbers and find the difference between them.

Starting with numbers 1 and 2, subtract the first from the second:

$-7-(-15)=-7+15=8$

That's a difference of 8, meaning the second number increased by 8.

Check the next numbers, 2 and 3:

$1-(-7)=1+7=8$

It increased by 8 again. Now that we know for sure that each term in the sequence increases by 8 over the previous one, we can find the number in the green box. Just add 8 to the number before it:

$9+8=17$
