# Brilliant is too famous. Isn't it? (fixed)

Algebra Level 2

A device named $$BRILLIANTOMETER$$ is launched which records the number of problems posted on Brilliant every second.IMAGINE that these problems were stored in a disc which had a limited capacity.

This was the data recorded by the brilliantometer -

In $$1^{st}$$ second - Total $$1$$ problem posted.

Till $$2^{nd}$$ second ends- Total $$2$$ problems posted.

Till $$3^{rd}$$ second ends- Total $$4$$ problems posted.

Till $$4^{th}$$ second ends- Total $$8$$ problems posted.

Till $$5^{th}$$ second ends- Total $$16$$ problems posted , and so on .........

If in 1 hour the disc was full and no more problems can be posted now , when was the disc half full? Express your answers in seconds.

I am extremely sorry for the inconvenience I caused to the people who solved this last time. I am re-posting this again.I am extremely sorry.
