A calculator used to take repeated square roots of a large number shows the sequence heading toward what?

1. The paper's example starts with an arbitrary large number and repeatedly finds the square root. 2. Each root brings the number closer to 1, so the sequence converges to 1. 3. It uses this to show the calculator's wider pedagogic value beyond arithmetic. _Source: NCERT National Focus Group Position Paper on Teaching of Mathematics, 5.1.3 Use of technology_
