Answer:
a(n) = 13 - 2n
Step-by-step explanation:
The explicit formula variables are a(n) = a(1) + d (n - 1). The a(1) is your number you started out with, and the d is the common difference. From the recursive formula example, you see that your first number is 11 and your difference is -2.
1. Plug the numbers into the equation : a(n) = 11 - 2 (n - 1)
2. Distribute: a(n) = 11 - 2n + 2
3. Add like terms: a(n) = 13 - 2n
If you want to double check, you can plug 1 into n and see if you get 11. I did this, and I did so it should be correct. Hope this made sense! Have a great day :)
Answer:
Step-by-step explanation:
To factorize, at first, do factorize all the terms then take the common terms out.
(a) 
This can be written as
Now, taking x commom from both the terms.
(b) 
Now, taking 
common from both the terms, we have
This is the required factorization.
(c) 
This is the required factorization.
(d) 
This is the required factorization.
