Question

Determine if the sequence 1, 2, 3, 5, 8, 13... is arithmetic, geometric, or niether.
A. Arithmetic
B. Geometric
C. Niether

Answer 1

is 1/2 the same as 2/3 ?

Answer 2

No

Answer 3

then which one can we rule out?

Answer 4

1/2

Answer 5

1/2 isnt an option :/

1/2 and 2/3 tell us something about a ratio between terms

Answer 6

does: 1-2 = 2-3 = 3-5 ?

Answer 7

Nope i get -1

Answer 8

1, 2, 3, 5, 8, 13

IF: 1/2 =2/3= 3/5 = 5/8 = 8/13 ; then the series would have a common ratio

IF: 1-2 = 2-3 = 3-5 = 5-8 = 8-13 ; then we would have a common difference

Answer 9

a common ratio is geometric; a common difference is arithmetic ... otherwise its none of them

Answer 10

so its neither
