How to find missing terms in a arithmetic sequence if there is no middle term?

Mathematics

kozerog [31]3 years ago

You would use the formula for the specific term you wish to find;
The formula is:
U_{n} = a + (n - 1)d
a = starting value of the sequence
d = the common difference (i.e. the difference between any two consecutive terms of the sequence)
n = the value corresponding to the position of the desired term in the sequence (i.e. 1 is the first term, 2 is the second, etc.)
Un = the actual vaue of the the term

For example, if we have the arithmetic sequence:
2, 6, 10, 14, ...
And let's say we want to find the 62nd term;
Then:
a = 2
d = 4
(i.e. 6 - 2 = 4, 10 - 6 = 4, 14 - 10 = 4;
You should always get the same number no matter which two terms you find the difference between so long as they are both consecutive [next to each other], otherwise you are not dealing with an arithmetic sequence)
n = 62

And so:
U_{62} = (2) + (62 - 1)(4) \\
= 2 + 61(4) \\
= 2 + 244 \\
= 246

Answer:

We can use excel regression data analysis tool to find the equation of the regression line that best fits the data.

The excel output is attached here.

Therefore, the equation of the linear regression is:

\hat{y}=21.9028+1.5736x

Where:

21.9028 is the intercept and 1.5736 is the slope.

Pls help

Answer:

Jimmy has a ratio of 1:20, or 1 page:20 seconds. Carlo has a ratio of 1:30, or 1 page:30 seconds. Jimmy reads at a faster pace than Carlo, as he is able to read a page in 2/3 of the time it takes Carlo.

Step-by-step explanation:

Jimmy reads a page, on average, every 20 seconds.

5 × 60 = 300

300/15 = 20

therefore, one page every 20 seconds

1:20

Carlo reads a page, on average, every 30 seconds.

6 × 60 = 360

360/12 = 30

therefore, one page every 30 seconds

1:30

suppose that maura continues to drive at her increased speed write an equation that represents the additional distance ,d ,in mi
Vlad [161]
Well for this equation if your trying to find the distances (d)
You need to know the speed (S) and the amount of hours (T)  she traveled

So your equation would look like this d= S* T
