Step-by-step explanation:
We have been given a recurrence relation and the first term of the sequence
.
We can rewrite the given recurrence relation as:
We know that if difference between two consecutive terms is always constant, the sequence is called an arithmetic sequence. So we are dealing with an arithmetic sequence with first term as 4 and common difference as 12.
We can therefore, write an explicit formula for nth terms of the sequence as.
This is the required explicit function rule for the given sequence.
