The first five terms of the recursive sequence an = an-1 + 7, where a1 = 5 can be found by applying the recursive formula multiple times.
Term 1: a1 = 5
Term 2: a2 = a1 + 7 = 5 + 7 = 12
Term 3: a3 = a2 + 7 = 12 + 7 = 19
Term 4: a4 = a3 + 7 = 19 + 7 = 26
Term 5: a5 = a4 + 7 = 26 + 7 = 33
About:
A recursive formula is a mathematical expression that uses a sequence of previously defined terms to define each successive term. This type of formula is commonly used to define sequences and can be used to define functions as well. The recursive formula is based on the idea of self-similarity, which means that each successive term is defined in terms of the one before it.
