There re 380 light bulbs lined up in a row in a long room. Each bulb has its own switch and is currently switched off. Each bulb is numbered and is consecutively from 1 to 380. You first flip every switch. You then flip the switch on every second bulb. You then flip the switch on every third bulb. This continues after you have gone the process 380 times

(I rlly need help)

Respuesta :

Flipping the bulbs is an illustration of sequence and patterns

19 bulbs would remain on.

How to determine the number of bulbs that will be on

The sequence of turning the bulbs off and on, would change the state of the bulbs until the 380th process.

While changing the state of the bulbs, the bulb at the perfect square positions would remain on.

There are 19 perfect square numbers between 1 and 380 (inclusive)

Hence, 19 bulbs would remain on.
