Acertain arithmetic sequence has this explicit formula for the nth term: an=12+ (n-1) (5) the same sequence has this recursive formula: an = an - 1 + hurry

Step-by-step explanation:

The given explicit formula for the nth term is:

Replace n by n - 1, we get,

But,

Therefore,

So,

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3

step-by-step explanation:

- (2, -7)

- lines r and s and lines t and u must be parallel
