The ratio of green to yellow beads is 4:5, and there are initially 27
beads. I add some yellow beads
and the ratio is now 1:3. How
many yellow beads did I add?

if the probability is 1/12, 75 people will receive a $25 gift card

step-by-step explanation:

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
