We will explain what this means in more simple terms later on and take a look at. The recursive formula is a formula used to determine the subsequent term of a mathematical sequence using one or multiple of the preceding terms. A geometric sequence is a sequence with the ratio between two consecutive terms constant.

Given the explicit formula. And it can be written as. Where a₁ is the first term and r the common ratio. An 54n1 a n 5 4 n - 1.
