Create an explicit formula for this sequence: 4,-1,-6, -11, ... O an = 4+ (n - 1)(5)
O
an = 4(5)(n-1)
O
an = 4(-5)(n-1)
O an=4+ (n - 1)(-5)

Afootball quarterback has two more chances to throw a touchdown before his team is forced to punt the ball. he misses the receiver on the first throw 25% of the time. when his first throw is incomplete, he misses the receiver on the second throw 15% of the time. what is the probability of not throwing the ball to a receiver on either throw?
