If both the President and Vice President can no longer serve, who becomes President?

If both the President and Vice president can't serve, for any reason, the Speaker of the House of Representatives would be next in line for President.

if the president dies, or cannot serve anymore, the people next in line would be:

whose power in the senate is equal to the power of the speaker of the house?

i would go with the last one
