Answer:


Step-by-step explanation:
Given

Required
Express as an exponential notation

Apply the following law of indices

This gives:


<em>The second complete is incomplete; However, I'll assume it is: 35 times 35</em>

Using the same law applied in (1) above:


Step-by-step explanation:
Given sequence is: - 3, 5, 13...
Here first term a = - 3
common difference d= 5-(-3)=13-5=8
Hence, it is in A. P.
Nth term of an AP is given as:

Which is the required formula for the given sequence.
Answer: Directly proportional
