Answer: i am prety sure that it is 8 because when you see that there is a plus sign a minus sign and an equeal thats pretty much all you gotta do.
Step-by-step explanation:
A formula is recursive if it expresses the term in terms of the previous one(s)
In this case, every term is 7 more than the previous one, so the formula for will only involve :
In fact, this formula is simply saying: for every index , the term with that index is 7 more than the term before.
Also, we have to specify the starting point (otherwise we would go backwards indefinitely), so the complete recursive formula is
which means: start with 2 and generate every other term by adding 7 to the previous one.
Answer:
Step-by-step explanation:
Since the formula for the area of a square is A = x^2, where x is the side length, x = √A.
If A = 64 square units, the side length is √64 units (8 units)
If A = 36 square units, that length is √36 units (6 units)
