A turbomachine airfoil element includes an airfoil that has pressure and suction sides spaced apart from one another in a thickness direction and joined to one another at leading and trailing edges. The airfoil extends in a radial direction a span that is in a range of 17.2-18.2 inches (436-462 mm). A chord length extends in a chordwise direction from the leading edge to the trailing edge at 50% span is in a range of 10.0-11.0 inches (255-281 mm). The airfoil element includes at least two of a first mode with a frequency of 51&#xb1;10% Hz, a second mode with a frequency of 147&#xb1;10% Hz, a third mode with a frequency of 267&#xb1;10% Hz, a fourth mode with a frequency of 350&#xb1;10% Hz, a fifth mode with a frequency of 454&#xb1;10% Hz and a sixth mode with a frequency of 619&#xb1;10% Hz.
