This page covers Agniveer Air Force Linear Seating Arrangement with complete concept notes, 22 graded practice MCQs, key points and exam-specific tips. Free to study.
Imagine people sitting on a bench in a straight line. Some face north (normal sitting), some face south (back towards north). You get clues about who sits where, how far from whom, and in which direction they face
💡Key Rules
1) Linear means straight line - either horizontal or vertical 2) People can face same direction or opposite directions 3) Left-Right is relative to the person's facing direction 4) Immediate left/right means directly adjacent 5) Between A and B means A and B are not adjacent.
🔢
Formula Block
Memorise — at least one formula appears in every paper
If n people sit in a line, total positions = n. If person A is 3rd from left, then A is (n-2)th from right. Distance between positions = |Position1 - Position2| - 1. If A faces north and B is to A's right, then B sits on A's right side. If A faces south and B is to A's right, then B sits on A's left side when viewed from above.

Exam Patterns
What examiners ask — read before attempting PYQs
→Common question types
1) Who sits at which position 2) How many people between two persons 3) Who faces which direction 4) Immediate neighbors identification 5) Position from left/right end
⚡Shortcut 1 - Direction Trick
When person faces north, their left-right matches your left-right. When person faces south, their left-right is opposite to your left-right
💡Remember
North facer's right = your right, South facer's right = your left
✏️Worked Example 1
1
R sits at position 1 (left end)
2
P sits at position 3 (given)
3
Q sits immediate right of P, so Q at position 4
4
S does not sit at right end (position 5), so S at position 2
5
T sits at remaining position 5
Final arrangement: R-S-P-Q-T (positions 1-2-3-4-5)
Shortcut 2 - Elimination Method: Start with definite positions first. Place people with clear position clues. Then use process of elimination for remaining people
✏️Worked Example 2
1
A sits at position 5 (2nd from right in 6-person line), faces south
2
B sits at position 3, faces north
3
C sits immediate left of A, so C at position 4
4
E sits between B and C, so E at position... wait, B is at 3, C is at 4, so E cannot sit between them as they are adjacent
🔑Re-check
E sits between B(3) and C(4) means there's an error in our arrangement
→Correct approach
If E is between B and C, and B is 3rd from left, then arrangement could be B-E-C. So B(3), E(4), C(5). But A is 2nd from right (position 5). This means A and C both at position 5 - impossible
→Re-reading
A at position 5, so C at position 4 (immediate left), E must be at position 2 (only position between B and C if we consider the linear sequence)
🔑Final check and arrangement
Position 1(?), B(2), Position 3(?), C(4), A(5), Position 6(?). E between B and C means E at position 3. Remaining positions filled by D and F
⚡Shortcut 3 - Reference Point Method
Pick one person with maximum clues as reference point. Build the entire arrangement around that person
⚠️#1 Common Mistake
Students confuse left-right when people face opposite directions. Always remember - when someone faces south, their personal left becomes your right when you view from above. Many students lose 2-3 marks just because of this directional confusion. Draw arrows to show facing direction to avoid this trap.
