Since they are geometric, (1/9)/t = t/(1/4)find the values of all pronumerals if these series are geometric
d) 1/4,t,1/9
e)y,2,6
Beat me to it haha..Since they are geometric, (1/9)/t = t/(1/4)
Cross multiply you get t^2 = 1/36
Square root both sides you get 1/6
therefore t = 1/6
Since they are geometric, 6/2 =2/y
Cross multiply you get 6y = 4
Divide both sides by 6 you get y =4/6 =2/3
Beat me to it haha..
