Find an explicit formula for the arithmetic sequence -15, 13, 31, 49
san4es73 [151]

Answer:

No solution (read below)

Step-by-step explanation:

Formula:

a_n = a_1 + (n-1)d

N is the term #

D is the common difference

First, let's find the common difference.

13 - (-15) = 28

Let's see if that checks out.

31-13 = 18

49 - 31 = 18

18 is not equal to 28

Since there is no common difference you cannot find the equation.

Please tell me if you made a typo and comment on my answer, then I can help you find the answer

Probability of an event happening is given by:
probability of an event happening=number of ways it can happen/total number of outcomes
number of random selection=40
total number of patients who did not leave against medical advice=52,560
thus the probability that at random selection none of the 40 patients left the treatment center against medical advice will be:
