Which recursive formula defines this sequence for n > 1?
Sergeeva-Olga [200]

Answer:

(B)a_n=a_{n-1}+3

Step-by-step explanation:

Given the sequence: 3, 6, 9, 12, 15, 18, ...

6=3+3

9=6+3

12=9+3

If we continue in like manner, we notice that the nth term (a_n) is an addition of 3 to the previous term (a_{n-1}).

Therefore (for n>1), the recursive formula which defines the sequence is:

a_n=a_{n-1}+3

The correct option is B

What is the area that she paints
Andre45 [30]
To determine this, we need to multiply 8 by 36 and 3 by 4 to get the total area.
8 x 36 = 288
3 x 4 = 12

Subtract the two to get the total area she is painting.
288-12 = 276
Your total area is 276 sq ft.
Your answer is D.)
