1) Examining this Sequence, we have an Arithmetic Sequence whose ratio is
r = -7/4, therefore we can fill in the gaps by adding each term to -7/4, so we have:

Since in an Arithmetic Sequence each term is obtained by adding or subtracting a common ratio, in this case, r= -7/4
2) To transform a mixed number into a fraction, we need to keep the denominator from the original mixed number, and write the numerator as the product of the denominator by the whole number and add to the numerator:

To turn an improper fraction into a mixed number we need to divide the numerator by the denominator and write the whole number and the fraction
