A series consists of some numbers such that the summation of the divisors of any number of that series is 1 less than twice of t

Varvara68 [4.7K]

Answer:

The 9th term of the series is 256

Step-by-step explanation:

Here we have the numbers as follows

1, 2, 4 from we have;

1 = The first term of the series

2 = The second term of the series

4 = The third term of the series

From the definition of the series, the sum of the factors is 1 less than twice the number, therefore, since 4 satisfies all the conditions, we observe that;

4×2×1 = 8 also satisfies all the conditions, hence we have;

8 = The fourth term of the series

8 × 2 = 16 = The fifth term of the series

16 × 2 = 32 = The sixth term of the series

32 × 2 = 64 = The seventh term of the series

64 × 2 = 128 = The eight term of the series

Therefore, the 9th term of the series = 128 × 2 = 256.

Four times the smallest of three consecutive integers is three more than three times the largest. What is the middle integer?

kozerog [31]

Let, first integer is x.

Therefore, other two are x+1 , x+2 .

Now, mathematical expression of given conditions is :

4x + 3 = 3(x+2)

4x + 3 = 3x + 6

x = 3.

So, the consecutive numbers are 3 , 4 and 5.

Therefore, the middle integer is 4.

Hence, this is the required solution.

Based on a recent poll, there is a 50-50 chance that randomly selected adut has pierced ears, Express the indicated degree of li

Neporo4naja [7]

Answer:

1/2 or 0.5

Step-by-step explanation:

Saying that there is a 50-50 chance of an event happening is equivalent to saying there is a 1 in 2 chance. Therefore, expressing that degree of likelihood as a value between 0 and 1:

$\frac{1}{2}=0.50$

There is a 1/2 or 0.5 chance that a randomly selected adult has pierced ears.
