1) in the first 2000 numbers , there are 44 squares. so when they are deleted , 2000 will become the 1956th term.
2025 is also a perfect square. So the 2000th term is 2045. 2003rd term is 2048.
2) a)0. which ever triangle u choose , there will be a right angle.
Frankly speaking , an expert should be able to do more than this.
