Find the 8th term of the geometric sequence -324, -108, -36, -12, . . .

Step-by-step explanation:

-108÷(-324)=0.333333333333 = 1/3

(-36)÷(-108)=0.333333333333

(-12)÷(-36)=0.333333333333

then the common ratio of the sequence is 1/3

then

the 5th term is 12×(1÷3) = 4

the 6th term is 4×(1÷3) = 1.333333333333

the 7th term is 1.333333333333×(1÷3) = 0.444444444444

the 8th term is 0.444444444444×(1÷3) = 0.148148148148

what is the original number? you forgot to add it.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
