Wriddhiman Saha is yet to score and Ishant Sharma is two not out.
Earlier, Gautam Gambhir was caught behind off Ryan Harris for three. Sehwag blasted his way to a half-century off 36 balls.
The Delhi thrasher took a huge swipe at a full toss from Lyon and top-edged a catch to cover for 62 after hitting 12 boundaries. Lyon looked embarrassed to claim the wicket.
Rahul Dravid (25) was caught at gully off Harris, ending a poor series in which the 39-year-old averaged 24.25.
Test cricket's leading runscorer, Tendulkar was caught at short leg off Lyon's bowling for 13 to make it 4-110.
The 38-year-old, who has been set to become the first player to score 100 international centuries since notching his 99th ton in March 2011, was given a standing ovation in what's likely to be his last Test appearance in Australia.
Sri Lankan umpire Kumar Dharmasena added to the drama by asking Tendulkar to wait for a video review of a possible no-ball before he was cleared to depart.
An Australian team spokesman confirmed the umpire was having trouble judging any possible no-balls because Harris's back foot blocked the umpire's view of his front foot.
Australia declared their second innings three overs after lunch at 5-167 with Ricky Ponting unbeaten on 60 and Brad Haddin 11 not out.
Skipper Michael Clarke contributed 37 and Mike Hussey made 15.
Clarke (125.2) and 37-year-old Ponting (108.8) averaged more than 100 for the series.
India would have to set a world record to win the fourth Test.
