Classify these sequences as arithmetic, geometric, or neither. Make sure to justify your answer 6) 7, 14, 28, 54

7) 1000, 200, 40, 8

8) 7, 14, 21, 28

thank u !

6) 7, 14, 28, 54 - geometric sequence

( multiplication with 2 )

7) 1000, 200, 40, 8 - geometric sequence

( division by 5 )

8) 7, 14, 21, 28 - Arithmetic sequence

( addition of 7 )

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
