Answer : The fifth term in the sequence is -2.
Step-by-step explanation :
As we are given that the expression to calculate the
term.
The expression is as follows:

where,
n is the number of term
Given:
n = 5
Now putting the value of n in the above expression, we get:




Therefore, the fifth term in the sequence is -2.
Answer: 2.14 %
Step-by-step explanation:
Given : pH measurements of a chemical solutions have
Mean : 
Standard deviation : 
Let X be the pH reading of a randomly selected customer chemical solution.
We assume pH measurements of this solution have a nearly symmetric/bell-curve distribution (i.e. normal distribution).
The z-score for the normal distribution is given by :-

For x = 6.74

For x = 6.76

The p-value =

In percent, 
Hence, the percent of pH measurements reading below 6.74 OR above 6.76 = 2.14%
