Answer:
Step-by-step explanation:
If we observe the given sequence, we find that the ratio of two consecutive terms is the same. i.e.
Such a sequence in which the ratio of consecutive terms remain the same is know as Geometric Sequence. Following formula is used to represent a Geometric Sequence:
Here:
is the general term. Using the value of n =1,2,3 ... will give us the term of the sequence.
is the first term which is 1.2 in this case.
r represents the common ratio which is 2.5.
Using these values we get:
This formula can be used to represent the given sequence.
