1 answer:
Answer: f(n+1) = 3 f(n)
Step-by-step explanation:
- A recursive formula is used to determine each term of a sequence using preceding term or terms.
Given sequence : 2.5, 7.5, 22.5, 67.5, 202.5,...
Here,
Common ratio = 3
Let f(n) be a term in this sequence then the next term will be f(n+1) = 3 f(n), where n is a natural number .
Required recursive formula : f(n+1) = 3 f(n)

Decimal form,
x=0,1.30766048......
Step-by-step explanation:
x=
x-
=0
(take x as a common factor)
x(-
)=0
So,
x=0 and -
=0
for -
=0
(add for both sides)
=
x= (multiply 3 by 2)
x=
So,
