what is a geometric sequence
is a sequence of numbers where each term after the first is found by multiplying the previous one
7 1/2 − 7/12
6 11/12
is this an equivalent ratio

explain the integer rules
ALL OF THEM
Multiplication & Division~ The product/quotient of a positive integer and a negative integer is negative, the product/quotient of two positive is positive, the product/quotient of two negatives is negative
Addition and Sundtraction~ two negatives equal a negative, two positives equal a positive, a positive and a negative you keep the sign of the greater number
Explain the difference between the sequences
An arithmetic sequence has a constant difference between each term.
For example: 2,4,6,8,10,12,…
A geometric sequence has a constant ratio (multiplier) between each term.
An example is: 2,4,8,16,32,…
Emir made trail mix for a backpacking trip. He used 5/9 of a pound of peanuts, 5/9 of a pound of chocolate chips, and 2/3 of a pound of raisins. How many pounds of trail mix did Emir make?
1 7/9 pounds
explain the term "Ratio"
A ratio between two or more quantities is a way to compared to each other
12=–2s – 12
