WHAT ARE RECURSIVE SEQUENCES:
A recursive sequence is a sequence where each term (tn) isdefined from earlier terms (tn-1 or tn-2) in the sequence.
2, 4, 6, 10, 16, 26, 42,….
The Fibonacci Sequence: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ……
Ex: Given that t1 = 0, t2 = 3 and tn= tn-1+2 (tn-2), find t7
Sum of the previous two terms
Product of the previous two terms minus one
