U.S. growth accelerated in the third quarter as consumers and businesses ramped up spending, a report that shows the economy remained resilient in the face of strong headwinds. Gross domestic product in the July-through-September period expanded at a 2.5% annual rate, the government said Thursday. That’s nearly double the 1.3% rate of growth in the second quarter and much faster than the first quarter’s tepid increase of 0.4%.
