Step-by-step explanation:
Here is the full question :
Arthur is organising his collection of DVDs He has 112 altogether. The ratio of comedy films to action to horror is 4 : 7 : 3
How many of each type of DVD does he have?
the number of each dvd arthur has = ratio / sum of ratios) x total number of DVDs
Sum of ratios = 4 + 7 + 3 = 14
Comedy films = (4/14) x 112 = 32
Action = (7/14) x 112 = 56
Horror = (3/14) x 112 = 24
Answer:
Explicit formula is an = 64(-3/4)^(n-1).
Step-by-step explanation:
Looks like a geometric sequence with a negative common ratio.
-48/64 = - 3/4
36 / -48 = -3/4
Now -27/36 = -3/4 so I think there's a typo in the question. Its -27 not -17.
The required formula is 64(-3/4)^(n-1) .
