Final answer:
The recursive definition of the sequence is a1 = -5 and an = an-1 + 4, while the explicit definition is an = -5 + 4(n-1). The 350th term of the sequence is 1391.
Step-by-step explanation:
Recursive definition: The sequence can be defined recursively as follows: a1 = -5 and an = an-1 + 4, where n > 1. In other words, each term in the sequence is obtained by adding 4 to the previous term.
Explicit definition: The explicit formula for the sequence is an = -5 + 4(n-1), where n represents the position of the term in the sequence.
To find the 350th term of the sequence, substitute n = 350 in the explicit formula:
a350 = -5 + 4(350-1) = -5 + 4(349) = -5 + 1396 = 1391.
