For the given statement Pn, write the statements P1, Pk, and Pk+1.

Leno4ka [110]

Answer:

$P_{1}$ = 2

$P_{k}$ = k(k+1)

$P_{k+1}$ = (k+1)(k+2)

Step-by-step explanation:

We are given the statement,

$P_{n}$ as 2 + 4 + 6 + . . . + 2n = n(n+1)

That is,

$P_{n}$ as 2 + 4 + 6 + . . . + 2n = $\sum_{i=1}^{n}2i$

So, we have,

$P_{1}$ = $\sum_{i=1}^{1}2i$ = 2

$P_{k}$ = $\sum_{i=1}^{k}2i$ = 2 + 4 + 6 + . . . + 2k = k(k+1)

$P_{k+1}$ = $\sum_{i=1}^{k}2i$ = 2 + 4 + 6 + . . . + 2k + 2(k+1) = (k+1)(k+2)

Thus, we get,

$P_{1}$ = 2

$P_{k}$ = k(k+1)

$P_{k+1}$ = (k+1)(k+2)

Min: 2 Q1: 7.5 Med: 11 Q3:14 Max:17

Step-by-step explanation:

Min is the minimum value of the provided data. In this case it is easier to tell because the numbers are arranged in ascending order;

The minimum value is;

= 2

Quartile 1 is the value that divides into half, the first half of the provides values. The first half of the value is divided by the median (In this case 11). The value that is halfway the values before median value is the Q1

In this case, we end up with two values because the numbers of values are even;

6 & 9

We sum the two and divide by 2

(6 + 9) / 2 = 7.5

Median is the value that is in the middle of all the provided values arranged in ascending order. Because the values are even, we end up with two numbers;

11 & 11

Again we sum the two and divide by 2;

(11 + 11) / 2 = 11

Quartile 3 is the value that divides into half, the second half of the provided values. This means the value three-quaters way. Because the number of provides values is even, then we end up with two values;

14 & 14

We sum the two and divide by 2

(14 + 14) / 2 = 14

Max value is the largest number of all the values;

= 17
