Sum of first 'n' consecutive odd integers= \(n^2\)
sum of all the positive odd integers less than 100= \(50^2\)=2500
sum of all the positive odd integers less than 302= \(151^2\)=22801
sum of all the odd integers between 100 and 302= 22801-2500= 20301
sum of all the positive odd integers less than 100= \(50^2\)=2500
sum of all the positive odd integers less than 302= \(151^2\)=22801
sum of all the odd integers between 100 and 302= 22801-2500= 20301
