i'm a noob, and i am having trouble adding resistors. this circuit can be reduced to 1 resistor. what is its value?

2. Relevant equations

parallel: 1/Rtot=1/R1+1/R2+1/R3+1/R4

series: Rtot=R1+R2+R3+R4

3. The attempt at a solution

so i thought 3, 2, 2 added up in series and you just do 6/8+1/4, but this isn't right. =/ i'm having trouble discerning which resistors are parallel and which are in series. any help would be appreciated.
