</span>4.) 1, 3, 5, 7, . . . -----------> <span>E.) An example of an infinite sequence
</span>5.) No first term is available -----------> C.) The reason the numbers . . . -4, -2, 0, 2, 4, . . . are not a sequence
Part 2
The answers is A.
Part 3
The answers is B.
Part 4
The pattern in this sequence is:
Let's list first six terms:
This is a infinite sequence. The patern is obvious and we could find any term within the sequence.
