Given the recursive formula, each terms is five time the previous one.
This means that:
In general, since you have , each time you compute a new term you multiply by a factor of 5, so if
, you have
Expression consists of numbers, variables, and mathematical operations. The expression f(w)=5(w+4) is equal to f(9)=5(9)+20.
<h3>What is an Expression?</h3>In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The expression is given to you is,
Now, if we solve the expression it can be written as,
substituting the value of w, we will get,
Hence, the expression f(w)=5(w+4) is equal to f(9)=5(9)+20.
