Leonard wrote the sequence of numbers below. 9, 15, 21, 27,... Which expression did be use to form the sequence, where n is the term number? A 3n + 3
B 3n - 3
C 6n+3
D 6n-3​

I think they took 3 * 3 is equals to 9

3 * 5 equals to 15

3 * 7 equals to 21

and 3 * 9 equals to 27.

Step-by-step explanation:

can can you realise that they skipped 3 * 4 3 * 6 and 3 * 8 and the difference between 9 and 15 is 6 meaning there's a gap of 6 at each sequence so I guess my answer is 3 and + 3 if it's not if this is not the answer please tell me if it is not matching with your book tell me so that i can ask the people around me. answer 3n + 3

n
