(4,7,12,19) How do you right this in recursive and explicit equations??????? pls help

Soloha48 [4]

You can see how the difference between two consecutive terms is constantly increasing:

$a_1 = 4$

$a_2 = 7 = 4+3$

$a_3 = 12 = 7+5$

$a_4 = 19 = 12+7$

So, for the next terms we'll have to add +9, +11, +13 and so on.

Also, note that $a_2$ is obtained by adding the 2nd odd number to $a_1$ , $a_3$ is obtained by adding the 3rd odd number to $a_2$ , and so on.

So, the recursive formula is

$a_n = a_{n-1}+(2n-1),\quad a_1=1$

For the explicit formula, recall that the sum of the first n odd numbers is n squared. Taking into account the fact that we're not starting from 1, we have

$a_n = n^2+3$

A class of 40 students took a test 20 students had an average score of 65. the other students had an average score of 52. what i

Korolek [52]

Answer:

One: 58.5

Two 36.6

Step-by-step explanation:

One

20 students * 65 = 1300 This is the total score of all 20 students. They may not all get 65, but 1300 is what their average total is.

20 students * 52 = 1040

The total score of all 40 students was 1300 + 1040 = 2340

The average for the entire class was 2340 / 40 = 58.5

Two

This question is done almost the same way.

Supposes the total number of members is 100. That means that 28 of them are men

28 * 33 = 924 This is the total age for the men

100 - 28 = 72 Out of 100, 72 of the people there are women.

72 * 38 = 2736

The total number of years of all of the members is

924 + 2736 = 3660

The average age of all members is 3660/100 = 36.6

Why did I pick 100 as the total membership? It is because a percentage is number out of 100. Am I allowed to invent things like that? Sure. I'm just using the definition of a percentage.

The average will make it come out the same.
