I think the probability of drawing a king card on the first draw is 1/12
Which recursive formula can be used to generate the sequence
below, where f(1) = 3 and n ≥ 1?
3, –6, 12, –24, 48
The recursive formula for this sequence is
f (n + 1) = –2 f(n)
at n=1 f(n)= 3
at n = 2
f(2) = -2 (3) = -6
n = 3
f(3) = -2 (-6) = 12 and so on
2 / 15 = 30 / x.....2 inches to 15 miles = 30 inches to x miles
could also be :
15 /2 = x/30...15 miles to 2 inches = x miles to 30 inches
either way, u will get the same answer
