Answer:  20

Step-by-step explanation:

Given the sequence {5, 10, 20, 40, 80, ... }

the first term (a₁) is 5

the second term (a₂) is 10

the third term (a₃) is 20

the fourth term (a₄) is 40

the fifth term (a₅) is 80

Answer:

[tex]a_{3}[/tex] = 20

Step-by-step explanation:

The first term in the sequence = 5

the second term = 10

the third term = 20

the fourth term = 40 and the fifth term = 80

In general the terms in the sequence can be denoted by [tex]a_{n}[/tex]

where n represents the position of the term in the sequence

[tex]a_{1}[/tex] denotes the first term

[tex]a_{2}[/tex] denotes the second term

[tex]a_{3}[/tex] denotes the third term and so on

Here [tex]a_{3}[/tex] = 20
