Question

Identify the type of sequence shown in the table below and select the appropriate response.


n f(n)
1 48
2 −96
3 192
4 −384
5 768


Arithmetic sequence; common difference is 96
Arithmetic sequence; common difference is −144
Geometric sequence; common ratio is 3
Geometric sequence; common ratio is −2

Answer 1

well, do you see the pattern in the table?

Answer 2

no not really

Answer 3

hint: start by dividing the second term by the first term

Answer 4

Hint :- you multiply to get the next number

Answer 5

umm those are 2 different hints

Answer 6

is it the second one

Answer 7

nvm i think its the first one

Answer 8

It's neither the first nor the second. The two hints are actually the same.
You divide the 2nd term by the 1st to get the ratio.

Answer 9

oh so then its the last one

Answer 10

Correct.

Answer 11

yes

Answer 12

thank you

Answer 13

each term is multiplied by -2 to get the next one.

Answer 14

yw

Answer 15

the general form of a geometric sequence is
a , ar , ar^2 , ar^3 etc

where a = first term and r = common ratio

Answer 16

the formula for the nth term is

an = ar^(n-1)
