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 )

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

gdp is the best phrase!
