The tension in the spring will be 5N.

Rather than explain why this is so, perhaps consider the situation where the tension is not 5N. In that event there would be a net force acting on some portion of the spring and that portion would be obliged to undergo acceleration. However, the entire spring itself would be in equilibrium because you say that its ends are pulled by a force of 5N.
