Question

What is the fifth term of a recursive sequence that follows the pattern 2x and has a first term x = 1?
i think it is 2

Answer 1

for x=1, 2x=2(1)=2
for x=2, 2x=2(2)=4
for x=3, 2x=2(3)=6
for x=4, 2x=2(4)=8
for x=5, 2x=2(5)=10
so you saying your pattern is 2,4,6,8,___
what goes in that blank, right?
the 5th term is 10

Answer 2

i think i don't really understand your question

Answer 3

if your first term is 1, how could it follow a 2x pattern unless it started with x=1/2 but x=1
2x=1 when x=1/2 not x=1
so i'm not sure of the question

Answer 4

the options are 2, 4, 8, and 16

Answer 5

i think 2x means multiply by 2 each time
1,2,4,8,16...

Answer 6

or an = 2^n

Answer 7

well, to me, the answer to be 2 makes sense. i just want to know if i'm right lol

Answer 8

well i don't think it would be 2
cow seems to have the right answer above

Answer 9

no the 5th term is 16
1,2,4,8,16...
