1, 3, 9, 27
5, 10, 15, 20

which goes with what sequence
A) Arithmetic, common difference is 5
B) Arithmetic, common difference is -3
C) Geometric, common ratio is 3
D) Geometric, common ratio is 0.25

Answer 2

do you know what "antithetic" and "geometric" mean?

Answer 3

lol "arithmetic"

Answer 4

yeah kinda but i dont really understand how to find them

Answer 5

artithmetic means you add or subtract the same number from one term to get to the next

Answer 6

so for example 5, 10, 15, 20 is arithmetic because you are adding the same number (namely 5) to each number to get to the next number

Answer 7

whereas geometric means you MULTIPLY or DIVIDE each number by the same number to get to the next one
for example 128, 32, 8, 2 is geometric because you divide each number by 4 to get to the next one

Answer 8

i will let you figure out the other two for yourself
one is arithmetic, one is geometric

Answer 9

thats not an option
