Answer:
97 and 98
Step-by-step explanation:
Anita first rode her bike 5 blocks to the east.
She then rode twice as many blocks west. 5*2=10. She rode 10 block west. Subtract 10 from 5: 5-10=-5
She finally rode 8 blocks back east. Add 8 to -5: -5+8=3.
Anita is three blocks east from home.
Answer:
Of(7) = f(1) + 24
Step-by-step explanation:
Since this Arithmetic Sequence can be written recursively as a function, then we can write the whole sequence, by adding the common difference to the previous function. So writing it as an Arithmetic formula is (placing an example, with a common difference of 4 units):

well there is 7x4, 14x2, and 28x1 of course.
You need to use the steps of a^2+b^2=c^2
A and B are the legs. C is the hypotenuse.
If we follow that through, we find the answer is 20.
