It is arithmetic.
It starts at - 5,
the next item is 0 then 5 and next is 15 ...
============
It isn't geometric. You are not multiplying by 5
The second term must be and not- 5 * 5 = - 25
============
A Fibonacci series adds the previous two terms together to get the next term
Usually it starts at 0, but it doesn't need to.
0,1,1,2,3,5,8,13,21,34 ....
Well use photo math that will give u the answer and how to work it out
A. See the picture for steps
Answer:
He bought 17 books.
Step-by-step explanation:
Given that:
Total money spent = $89
Cost of each book = $5
Shipping price = $4
We have to find, Total number of books
So if the number of books be represented by b, the equation will become:
Cost of one book * total number of books + shipping price = total money
Putting values we get:
5*b + 4 = $89
By simplifying:
5*b = 89 - 4
5*b = 85
Dividing both sides by 5 we get:
b = 17
So the total number of books bought is 17.
i hope it will help you!
