Given the list of terms 1/3​, 1, 5/3, 7/3,.... Find the 15th and −16th term.
qwelly [4]

Answer:

15th term =29/3

16th term = 31/3

Step-by-step explanation:

Given an arithmetic sequence with the first term a1 and the common difference d , the nth (or general) term is given by an=a1+(n−1)d .

First we find the 15th term

n=15

a1=1/3

d=1 - 1/3 = 2/3

Solution

1/3+(15-1)2/3

1/3+28/3

(1+28)/3

29/3

Lets find the 16th term

1/3+(16-1)2/3

1/3+30/3

(1+30)/3

31/3

Four usual dice are thrown on the ground. The total of numbers on the top faces of these four dice is 13 as the top faces showed
NikAS [45]

The total of the faces touching the ground is 15.

<h3 /><h3>What is probability?</h3>

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.

Given that:

Four usual dice are thrown

Total of numbers on the top faces of these four dice = 13

we know that in a dice, the sum of the numbers on any two opposite faces is always 7.

So,1 is opposite 6,

2 is opposite 5

and 3 is opposite 4.

Now, when 4,3,1 and 5 are the numbers on the top faces, then 3,4,6 and 2 respectively are the numbers on the face touching the ground as they sum upto 7.

Hence, total o faces touching the ground =3+4+6+2=15.
