<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
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
