A quick check shows it is neither arithmetic nor geometric, so mess around with it a bit
how about (1/18)( 12, 6, 4, 3, ....) , 18 is the LCD
notice :
12/1 = 12
12/2 = 6
12/3 = 4
12/4 = 3
so it looks like
term(n) = (1/18)(12/n) = 2/(3n)
2/3, 1/3, 2/9, 1/6
Create an explicit formula for this.
Is it an arithmetic or geometric sequence?
