Answer:
20-2(n-1)
Step-by-step explanation:
The general term (or the nth term) of this sequence is [20-2(n-1)].
Verification:
1st term = 20-2(1-1) = 20-2(0) = 20-0 = 20
2nd term = 20-2(2-1) = 20-2(1) = 20-2 = 18
3rd term = 20-2(3-1) = 20-2(2) = 20-4 = 16
4th term = 20-2(4-1) = 20-2(3) = 20-6 = 14

Answer:
x=55
Step-by-step explanation:
Answer:
a = c/(d - r)
Step-by-step explanation:
Multiply both sides by a
(c/a)a = (d - r)*a Notice how this is written. You need to introduce brackets on the right because both d and r are multiplied by a.
c = (d - r)*a
Divide both sides by (d - r)
c/(d - r) = a*(d - r)/(d - r)
c/(d - r) = a
