4.2 The first two terms of a geometric sequence and an arithmetic sequence are the same. The first term is 12. The sum of the first three terms of the geometric sequence is 3 more than the sum of the first three terms of the arithmetic sequence. Determine TWO possible values for the common ratio, r, of the geometric sequence. (6) [11]

Summary. A sequence is a set of numbers in a given order with a rule for obtaining the terms, written as: . The nth term of a sequence is an expression that will allow us to calculate the term that is in the nth position of the sequence i.e is the first term of the sequence, is the second term and so on.; A sequence is called convergent if there is a real number that is the limit of a sequence.
