Final answer:
The sequence generated by the given recursively defined equation t(n+1) = t(n) - 6, with an initial condition of t(1) = 60, is 60, 54, 48, 42, ...
Step-by-step explanation:
The given recursively defined equation is t(n+1) = t(n) - 6, with an initial condition of t(1) = 60.
To find the sequence generated by this equation, we can start with the initial value of 60, and for each subsequent term, subtract 6 from the previous term.
So, the sequence is: a. 60, 54, 48, 42, ...
