is the sequence 10,2 qeometric? if so what is r?

Question

amistre64 · Answer

there is not enough information to form a sufficient pattern from recognition

amistre64 · Answer

but if it were geometric, then r is a common ratio of terms such that:  r = a2/a1

anonymous · Answer

is th e sequence 10,2 geometric. if so find r
2/5
2/25

amistre64 · Answer

10,2  could be the start of an arithmetic sequence in which we subtract 8 each time

10,2,-6,-14,...

-------------------------------

10,2  could be the start of a geometric sequence in which we multiply by 2/10

10, 2, 2/5 , 2/25,...

--------------------------------

10,2  could be the start of a random sequence

10,2,-5,32,13,48,-2,...
