- The first three terms of an AP are respectively 3y-1, 3y+5 and 5y+1. Then calculate the value of y.
- The first three terms of an AP are respectively 3y-1, 3y+5 and 5y+1. Then calculate the value of y.
In an AP: difference b/w successive terms =constant
thus: 3y+5-(3y-1)=5y+1-(3y+5)
thus:6=2y-4
thus y=5
thus, 14,20,26
