Which recursive formula defines this sequence for n &gt; 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

4)

12/16=21/b

multiply both sides by b
(12/16)b=21

now multiple both sides by (16/12)
b = 21 (16/12) =28

5)
rate is distance / time or time/distance

train travels 279 km per 1.5 hr =270/1.5
or
1.5 hr per 270 =1.5/27p

answer choice a and c matches that.
looking at choice C...270km/1.5hr=5hr/270km

looking at choice A.. 1.5hr/270km=5hr/k km

the units don't match for choice C so the

right answer is A

6)

1.5/270=5/k

multiply both sides by k
(1.5/270)k=21

now multiple both sides by (270/1.5)
k = (270/1.5)21= 900

7) 75 points per 6 game

75 points / 6 games

75/6=P/20

multiply both sides by 20
(75/6)20=P

P=250
