Answer:
B
Step-by-step explanation:
Answer:
Solution,
First term (a) = 25
Common difference (d) = Second term - first term = 20 - 25 = -5
Now,
nth term = a + (n - 1)d = 25 + (n - 1) (-5) = 25 - 5n +5 = 30 - 5n
The nth term of the series is 30 - 5n
Answer:
its 6
Step-by-step explanation:
F(1)=18
f(2)=18-2=16
f(3)=16-2=14
f(4)=14-2=12
f(5)=12-2=10
Answer: y = 800
Step-by-step explanation:
3(y+200) = 3000
y+200 = 1000 (dividing 3 from both sides)
y = 800
