Use words and symbols to describe the value of each term as a function of its position. Then find the value of the twelfth term in the sequence.

21 for the first one, 144 for the second

Step-by-step explanation:

If you're seeing the same problem I am in class, the rule is: N + 9

N is equal to 12 in this equation

12 + 9 is 21.

So, the answer is 21

If there is a second problem, like there is for the one I'm seeing, then this is the answer for that-

Is 12(12)= 144

Hope this helps!

(By the way, I'm horrible at math so this could be completely wrong)

never fear papaguy is here

answer

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
