Answer:Step-by-step explanation:
If there is a sequence and if we are to find its 87th term we must have the general term formula for the sequence.
Normally for sequences which follow a pattern there will be a formula for nth term.
Example is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference.
Similarly for geometric sequence nth term
= is the nth term
Thus to find the 87th term, we must be able to find out the pattern of the sequence by which any term is related to its previous term
Either general term formula or recurring formula should be given to get the 87th term
Step-by-step explanation: is arithmetic sequence nth term = a+(n-1)d where a is the I term and d the common difference. Still stuck? Get 1-on-1 help from an expert tutor now.
Answer:
Brand 1 Brand 2 Difference
37734 35202 2532
45299 41635 3664
36240 35500 740
32100 31950 150
37210 38015 −805
48360 47800 560
38200 37810 390
33500 33215 285
Sum of difference = 2532+ 3664+740+150 −805+ 560 +390 +285 = 7516
Mean = 
Mean = 
a) d= 939.5
=1441.21
b)SD= 1441.21
c)Calculate a 99% two-sided confidence interval on the difference in mean life.
confidence level =99%
significance level =α= 0.01
Degree of freedom = n-1 = 8-1 =7
So,

Step-by-step explanation:
When dividing exponential terms of the same base, we can simply subtract the exponents, therefore:
Answer is D.x=9
5x+3+6x+5+8x+1=180
now solve for 'x'
