Answer:
The n th of the given sequence is 
Step-by-step explanation:
<u>Step 1</u> :-
Given sequence is 20,14,8,2,.......this sequence in arithmetic progression but this sequence is decreasing sequence.
given first term is 20 and difference is
now the nth term of given sequence is
by using formula 


final answer:-

<u>verification</u>:-

put n=1 we get first term is 20
put n=2 we get second term is 14
put n=3 we get third term is 8
put n=4 we get fourth term is 2
so the n th term of sequence is

Answer:
slope is 4
Step-by-step explanation:
0.5% or 1/2% of say "x" is 250, whilst "x" is the 100%.
![\begin{array}{ccll} \%&amount\\ \cline{1-2} \frac{1}{2}&250\\[1em] 100&x \end{array}\implies \cfrac{~~ \frac{1}{2}~~}{100}=\cfrac{250}{x}\implies \cfrac{1}{200}=\cfrac{250}{x}\implies x = 50000](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7Bccll%7D%20%5C%25%26amount%5C%5C%20%5Ccline%7B1-2%7D%20%5Cfrac%7B1%7D%7B2%7D%26250%5C%5C%5B1em%5D%20100%26x%20%5Cend%7Barray%7D%5Cimplies%20%5Ccfrac%7B~~%20%5Cfrac%7B1%7D%7B2%7D~~%7D%7B100%7D%3D%5Ccfrac%7B250%7D%7Bx%7D%5Cimplies%20%5Ccfrac%7B1%7D%7B200%7D%3D%5Ccfrac%7B250%7D%7Bx%7D%5Cimplies%20x%20%3D%2050000)
Answer:
The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles
Step-by-step explanation:
Average speed = 400 miles per hour
Distance = 400t
t= 5
Total distance = 400t at t hours
Total distance when t = 5 hours
Total distance traveled = 400t
= 400 × 5
= 2,000 miles
Total distance travelled = 2,000 miles
The distance traveled by the B737-400 aircraft in 5 hours is 2,000 miles
hope this helps
