If you parallel two 100 ohm 1/4W resistors, you get a 50 ohm 1/2W equivalent resistor. Resistors in series add in resistance and the power dissipation doesn't change, if they're 1/4W, they're still 1/4W.

The individual resistors are still 1/4 watt but the voltage is divided in half,thus using Ohms law each resistor uses half the power.

That's what the word "equivalent" indicates.
