Answer:if it's proportional, it should not pass through the origin
Step-by-step explanation:
Answer:
3n^2
Step-by-step explanation:
3, 12, 27, 48, 75
List the differences between terms:-
9, 15, 21, 27
Now find the second differences:-
6, 6, 6
The sequence in the question is quadratic and the first coefficient ( that of n^2) = 6/2 = 3. The first term in the nth term formula is 3n^2.
Now we write out the original sequence and the 3n^2 values as follows:-
3 12 27 48 75
3 12 27 48 75
They are the same so the formula for the nth term is 3n^2.
I know it’s A, B, and E
For A you divide 24 by 3
For B you divide 56 by 7
And those both give 8
For C you divide 17 by 9 which isn’t 8.
For D I think you’d subtract 13 from 21 which is 8 but then the equation is -x = 8 so to change x i think then it’d be x = -8
so I don’t think D is right but i’m not 100% sure

By the way that it is worded, I believe that you are only allowed to put 1 charm on the bracelet, so there are 9 ways to pick a charm.
Hope this helps(and also if you have a more refined wording please put it in the comments)!
