In the linear rule (A(n)=22+4n), what is the initial value?
Answer and explanation
Correct answer: 22
The initial value is the value when the independent variable is zero. Putting \(n=0\), we get \(A(0)=22+4(0)=22\), so 22 is correct. Here, 4 is the rate of increase per unit of \(n\), while 26 is the value at \(n=1\). Exam tip: In a linear rule \(a+bn\), the initial value is the constant term \(a\).
