Given:

The sequence is:

2, 6, 10, 15,...

To find:

Whether the given sequence is Arithmetic, Geometric, Neither.

Solution:

We have,

2, 6, 10, 15,...

Different between consecutive terms are:

6-2=4

10-6=4

15-10=5

Since 4\neq 5, therefore the given sequence has no common difference. It means it is not an arithmetic sequence.

Ratio of consecutive terms are:

\dfrac{6}{2}=3

\dfrac{10}{6}=\dfrac{5}{3}

Since 3\neq \dfrac{5}{3}, therefore the given sequence has no common ratio. It means it is not a geometric sequence.

Since the given sequence is neither arithmetic nor geometric, therefore the correct option is C.

I need a better explanation how to find length and area of a triangle
fomenos

Answer:

Height(h) = 24in

Area = 204in²

Step-by-step explanation:

we would use the heron formula because we have all the sides to calulate the area

S  = (A+B+C)/2 = (25 + 17 + 26)/2 = 68/2 = 34

area = √s(s-a)(s-b)(s-c)  = √34(34-25)(34-17)(34-26) = √34(9)(17)(8) = √34x9x17x8 = √41616 = 204

area= (1/2)bh

    204 = (1/2)bh b= 17, h =?

204 = (1/2)17h

204 x 2 = 17h

408 = 17h

h = 408/17 = 24in

Height(h) = 24in

Area = 204in²

A.
Let x = age of Samantha.
Then x - 2 = age of Emily,
and x + 2 = age of Lauren.

b.
x - 2 + x + x + 2 = 42

c.
x - 2 + x + x + 2 = 42

3x = 42

x = 14

x - 2 = 14 - 2 = 12

x + 2 = 14 + 2 = 16

The ages of the sisters are 12, 14, 16.

Find the slope of the line passing through (-4,6) and (10,8)
muminat

Answer:

1/7

Step-by-step explanation:

In order to determine the slope, we must find the change in y over the change in x:

\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  } = \frac{8-6}{10--4} = 2/14= 1/7.

Therefore, the slope between these two points is 1/7.

What is 12.25 as a fraction
Finger [1]

Answer:

\large\boxed{12.25=\dfrac{49}{4}}

Step-by-step explanation:

12.\underbrace{25}_{2}=\dfrac{1225}{1\underbrace{00}_2}=\dfrac{1225:25}{100:25}=\dfrac{49}{4}\\\\12.25=12+0.25=12+\dfrac{25}{100}=12+\dfrac{25:25}{100:25}=12+\dfrac{1}{4}\\\\=\dfrac{12\cdot4}{4}+\dfrac{1}{4}=\dfrac{48+1}{4}=\dfrac{49}{4}
