Question

Which explains why the sequence 64, 4, 1/4,... is arithmetic or geometric? person to get it right gets five dollars on cash app

Answer 1

arithmetic sequence decreases by adding or subtraction a number exg 2,4,6,8

geometric sequence is mu;ltipliying or dividing by a number exg
2,4,8,16,32 etc


so it from 64 to 4 then to 1/4
64/16=4
4/16=1/4
it decreases by a factor of 1/16
it is geometric

the answer is B

Answer 2

This is a geometric sequence. Notice how 64*1/16 is 4, and 4*1/16 is 1/4. So the common ratio is 1/16. As for the money, no thanks.

You can make an equation like 64(1/16)^n-1 to represent the sequence
