Notice that during first 5 years, this saving plan works as a standard Ordinary Annuity, and you can calculate its future value after 5 years using standard formula FV(in 5 years) == 140927.324. In the 6th year, there is no deposit/withdrawal, so this amount grows in the 6th year as an one-time deposit with the growth coefficient 1.06. It gives the final amount after 6 years as 140927.324*1.06 = 149382.96. So, the ANSWER is the same as in the post by @KMST.
