Question

Which explains why the sequence 64, 4, 1/4,......is arithmetic or geometric?

A. The sequence is geometric because it decreases by a factor 1/16
B. The sequence is arithmetic because it decreases by a factor of 1/16
C. The sequence is geometric because it increases by a factor of 4
D. The sequence is arithmetic because it decreases by a factor of 4.

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

th enaswer is B
