Answer:
a(n) = 7 + 3(n - 1)
Step-by-step explanation:
Notice that every term of the sequence 7, 10, 13, 16 is 3 more than the previous term. That tells us this is an arithmetic sequence with first term 7 and common difference (d) 3.
Adapting the given equation, we end up with
a(n) = 7 + 3(n - 1)
Answer:1/9
Step-by-step explanation:
Simplified:
1/3 x 1/3
1/9
I am pretty sure x is 9 because if you divide 14 by 2 you get 7. 18 divided by 2 is 9.
