Suppose you are in an elevator. as the elevator starts upward, its speed will increase. during this time when the elevator is moving upward with increasing speed, your weight will be:

increased

Explanation:

It is given that elevator speed is increasing while moving upward i.e.its acceleration is increasing .

This causes the apparent to be increased if measured using weighing machine.

considering upward direction to be positive

N-mg=ma

N=m(g+a)

where N=Normal reaction=Apparent weight

a=acceleration of Elevator

thus you feel as if your weight is increased.
