Problem ID: PRABK2AZ 1. Use the first five terms of sequence
to define the sequence recursively using function notation.
2.5, 7.5, 22.5, 67.5, 202.5,...

f(n+1) = 3 f(n)

Step-by-step explanation:

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)

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
