sattari [20]
<h3>Answer: Choice D. 2, 6, 12, 20</h3>

=============================================

Work Shown:

Plug in n = 1

c(n) = n(n+1)

c(1) = 1(1+1)

c(1) = 1(2)

c(1) = 2

The first term is 2

-------------

Plug in n = 2

c(n) = n(n+1)

c(2) = 2(2+1)

c(2) = 2(3)

c(2) = 6

The second term is 6

-------------

Plug in n = 3

c(n) = n(n+1)

c(3) = 3(3+1)

c(3) = 3(4)

c(3) = 12

The third term is 12

-------------

Plug in n = 4

c(n) = n(n+1)

c(4) = 4(4+1)

c(4) = 4(5)

c(4) = 20

The fourth term is 20

-------------

The first four terms are: 2, 6, 12, 20

Please help me solve this!!
Studentka2010 [4]

Answer:

WR = 26

Step-by-step explanation:

Givens

UT = 10

VS = 18

WR = ??

Formula

(WR + UT) / 2 = VS

Solution

Substitute

(WR + 10) /2 = 18

Multiply both sides by 2

(WR + 10/2 * 2 = 18 * 2

Do the multiplication

WR + 10 = 36  

Subtract  10 from both sides

WR + 10 - 10 = 36 - 10

WR = 26
