Answer:
25a^2b^4c^2
Step-by-step explanation:
step 1:
Remove the bracket by multiplying all the power inside the bracket with the power outside the bracket.
5^2a^2b^2x2c^2=25a^2b^4c^2
Answer:
(-3, 4)

yeah
Recursive formula is: 
Explicit formula is: 
Step-by-step explanation:
Given sequence is:
15,11,7,3,-1
Here

First of all, we have to find the common difference
Common difference is the difference between consecutive terms of an arithmetic sequence
So,

<u>Recursive Formula:</u>
A recursive formula is used to find the next term of an arithmetic sequence using previous term and common difference
General form of recursive formula for a given common difference d is:

Putting the value of d

<u>Explicit Formula:</u>
The explicit formula is given by:

Putting the first term and common difference

Hence,
Recursive formula is: 
Explicit formula is:
