Alan, with 3 cards held (10d Qd Ad), the chance of getting a royal flush (TJQKA,TKQJA) is 1 in 1,081. However only one of these (TJQKA) is good for the Sequential so that the odds of a Sequential from this hold are 1 in 2,162 (2 x 1081). 1/2162 of $210,000 gives an EV of 97.13. Of course (from this 3-card hold), you can also pick up a variety of other non-losing hands such as the non-Sequential royal which has an EV of 1.85 (1/2162 of $4000), high card pairs (240/1081), two pairs (27/1081), three of a kinds (9/1081), straights (15/1081) and other flushes (43/1081 since one of them was thrown away) besides the one that was thrown away. So the EV of the 3-card hold is greater than 97.13. If the flush is held, the EV is 25. So the correct hold is the 3 card hold versus the pat flush.
