question 144

Multiple Choice

Find a general term an for the geometric sequence.
- $$\mathrm { a } _ { 1 } = \frac { 1 } { 2 } , \mathrm { r } = 2$$

• A) \(a _ { n } = \frac { 1 } { 2 } \cdot 2 ^ { n - 1 }\)
• B) \(a _ { n } = \left( \frac { 1 } { 2 } \right) n - 1 + \frac { 1 } { 2 }\)
• C) \(\mathrm { a } _ { \mathrm { n } } = \frac { 1 } { 2 } + \frac { 1 } { 2 } ( \mathrm { n } - 1 )\)
• D) \(a _ { n } = \frac { 1 } { 2 } + 2 ( n - 1 )\)

Definitions:

Genotype

Genotype refers to the genetic makeup of an organism; it is the set of genes that an organism carries.

Genetic Composition

Refers to the complete set of genes within an organism's genome, including all of its genetic material.

Genetic Variation

The diversity in gene frequencies within a population, which contributes to the population's ability to adapt to varying environments.

Traits

Traits are distinguishable qualities or characteristics of an organism, ranging from physical attributes to behavioral patterns, largely determined by genetic information.
