Tick out the true statement about the Fibonacci Sequence.

The Fibonacci sequence consists of odd numbers only
A term in the Fibonacci sequence is always less than the one preceding it
A term in the Fibonacci sequence is a multiple of the two preceding ones
A term in the Fibonacci Sequence is the sum of the two preceding ones

The first and last terms in any row in the Pascal Sequence consist of

1 only
even numbers only
any number
multiples of 3
