The pattern is 0-1-2, 1-3, 2-3-4 index finger on 1st fret
median on the second, annular on the third and pinky on the fourth fret.
Shift to index finger on 2nd fret and median on the second etc..
Repeat this till index finger is on the 14th fret.
Repeat this exercise on 2nd string...upto 6th string.
Initially be slow and slowly increase the tempo to mad speed as you get familiar...always give stress to proper tone especially be careful not to slide or sloppy the pinky note.
