write a rule for the sequence. 5, -4, -13, -22,...
a: start with -9 add 5 repeatedly
b: start with 5 and add 9 repeatedly
c: start with 5 and subtract -9 repeatedly
d: start with 5 in a -9 repeatedly
2: find the next three terms of the sequence. -4,-8, -16 , -32...
a: -96, -288, -864
b: -64, -128, -256
c: -64, -288, -256
d: -36, -40, -44
help pls i think
it’s b and c
1D
If #1D is start with 5 and add -9 repeatedly.
2B
I guess you confuse multiplication with addition. or something ...
Plz help I'm failing math!!!!!!
#1. Not B -- that would be 5,14,23,...
#2. Not C. look at the sequence, and you can see that you keep multiplying by 2, but -64 * 2 ≠ -288
I suspect you are just guessing.
Hope this helps!!

Somebody plz tell me if this is right
No it's not, for me I have different answers someone please tell us the answer. By the way 'Mom' might be right for others.
Yo rosetta bush I have different questions on my test not those questions.
A cheetah travels at a rate of 90 feet per second.
The distance d traveled by the cheetah is a function of seconds traveled t. Write a rule for the function. How far will the cheetah travel in 25 seconds.
D=r×t
D=90t
D=90×25
D=2250 feet
