Write an Expression for the Apparent Nth Term of the Sequence

question 123

Multiple Choice

Write an expression for the apparent nth term of the sequence. (Assume that n begins with 1.) $$- 5 - \frac { 2 } { 1 } , - 5 - \frac { 2 } { 2 } , - 5 - \frac { 2 } { 3 } , - 5 - \frac { 2 } { 4 } , - 5 - \frac { 2 } { 5 } ,$$

• A) \(a _ { n } = - 5 - \frac { n } { 2 }\)
• B) \(a _ { n } = 2 - \frac { - 5 } { n }\)
• C) \(a _ { n } = 2 - \frac { n } { - 5 }\)
• D) \(a _ { n } = - 5 - \frac { 2 } { n }\)
• E) \(a _ { n } = - 5 - \frac { 2 } { n + 1 }\)

Definitions:

Chi-Square Distribution

A statistical distribution that is used to determine the goodness of fit of an observed distribution to an expected one under the null hypothesis.

Critical Value(s)

Specific point(s) on a distribution curve that define the threshold for rejecting the null hypothesis in hypothesis testing.

Level Of Significance

A threshold in hypothesis testing below which the null hypothesis is rejected, indicating statistical significance.

P-Value

The probability of obtaining a test statistic at least as extreme as the one observed during a test, assuming the null hypothesis is true.
