Answer:
(a+b)^2 = a^2 + 2ab + b^2
(a-b)^2 = a^2 - 2ab + b^2
(a-b)(a+b) = a^2 - b^2
Step-by-step explanation:
They differ because you can either add the property or multiply
The explicit formula of the arithmetic sequence:

d - common difference
We have the recursive formula of an arithmetic sequence:

Therefore we have:

Substitute:

<h3>Answer: aₙ = 7 - 3n</h3>
