Answer. The y-value increases by 5.
Reason:- let x=0 then, y=5*0-7
y=-7
now, x= then, y=5*1-7
y=5-7=-3
now, x=2 then, y=5*2-7
y=10-7=3
now, x=3 then, y=5*3-7
y=15-7=8
so, the series -7,-3,3,8….. is showing the difference of 5 between two numbers and also this series is in the increasing way
so, this series shows increment by 5.
