The fifth term of a sequence that is represented by f(n) = 5n - 2 will be 23.
A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The sequence is formulated in the function f(n) is given as,
f(n) = 5n - 2
The fifth term of a sequence is calculated as,
f(5) = 5 x 5 - 2
f(5) = 25 - 2
f(5) = 23
The fifth term of a sequence that is represented by f(n) = 5n - 2 will be 23.

The expression for the total cost of hiring a plumber will be equal to $50 + $40(h).
Mathematical actions are called expressions if they have at least two terms that are related by an operator and include either numbers, variables, or both. Adding, subtraction, multiplying, and division are all reflection coefficient operations. A mathematical operation such as reduction, addition, multiplication, or division is used to integrate terms into an expression.
As per the given statement in the question,
The charge for a plumber to visit the house = $50
The additional charge per hour = $40
The expression for t hours will be,
A = $50 + $40(h),
Here, A is the total amount and h is the number of hours the plumber is working.
