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.
1) Split the second term in into two terms.
2) Factor out common terms in the first two terms, then in the last two terms.
3) Factor out the common term
