SUPPOSE,R1=5OHM, R2=6OHM R3=4OHM SO R4=?
IN SERIES, THE RESISTANCE IS 1/R,SO,
R1+R2+R3+R4=MORE THEN R1+R2+R3
SO, RESISTANCE IS INCREASE.

Before three resister which conection.

In series combination R = R1+R1+R3+R4+ .... Rn.

So resistance will surely increase

R=R1+R2=R3+R4+............Rn

So resistance will increase.

We know that in series combination R = R1+R1+R3+R4+ .... Rn.

So resistance will increase.

The effective resistance in series is the sum of resistance. Therefore if a resistance is added in series,the overall resistance will increase. Answer-INCREASES

In series Rt=R1+R2+R3+R4+ ...

R1=4ohms;R2=3ohms Since it is connected in series.
R=4+3=7ohms. Ans.Increases.
