A sequence is defined by f(1)=-3, f(n)=f(n-1)+0.5 for n2. Diego write an equation for the nth term of the sequence as f(n)=-3+0.5(n-1) for n1. Is he correct? Explain your reasoning.
A sequence is defined by f(1)=-4, f(n)=f(n-1)-2 for n2. Write an explicit definition for the nth term of the sequence.
