Answer:

#1/24#

Explanation:

In this sequence, it seems that you divide the number by #2# to get the next one in the sequence. Therefore, you would divide the last given number in the sequence, #1/12#, by #2#. Then it's just simple math.

#(1/12) / (2) = (1/12) xx (1/2) = 1/24#

Answer:

#a_5=1/24#

Explanation:

#"these are the terms of a "color(blue)"geometric sequence"#

#a,ar,ar^2,ar^3, ...... ,ar^(n-1)#

#"where a is the initial term and r is the common ratio"#

#•color(white)(x)ar^(n-1)larrcolor(blue)"is the nth term"#

#•color(white)(x)r=a_2/a_1=a_3/a_2=...... =a^n/a^(n-1)#

#"here "r=(1/3)/(2/3)=(1/6)/(1/3)=(1/12)/(1/6)=1/2#

#rArra_5=2/3xx(1/2)^4=2/3xx1/16=2/48=1/24#
