Is the sequence 5, 9, 15, an arithmetic sequence? Explain.

igor_vitrenko [27]

Answer:

Step-by-step explanation:

An arithmetic sequence has a common difference between adjacent terms. Here, the differences are ...

9 -5 = 4
15 -9 = 6

The differences are different, not common, so this is NOT an arithmetic sequence.

Find the value of r so the line that passes through the pair of points has the given slope.

SOVA2 [1]

Answer:

The missing value in the ordered pair is 66

Step-by-step explanation:

Given that:

(12,10) and (-2,r)

Slope = m = -4

We have to find the value of r so that the line has a slope of -4.

Slope is the steepness of line which is denoted by m.

Here,

$x_1=12, y_1=10\\x_2=-2, y_2=r$

Putting the values in slope of line formula,

$-4=\frac{r-10}{-2-12}\\ -4=\frac{10-r}{-14}\\$

Multiplying both sides by -14

$-4*-14=\frac{r-10}{-14}*-14\\56=r-10\\56+10=r\\66=r\\ r=66$

The value of r is 66

Hence,

The missing value in the ordered pair is 66
