Odd numbers b/w 0-30:
1,3,5,........29.
1,3,5,........29.a=1
1,3,5,........29.a=1d=3-1=2
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)d
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)2
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-2
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n30= 2n
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n30= 2n15= n
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n30= 2n15= nalso, sum =n/2(a+l)
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n30= 2n15= nalso, sum =n/2(a+l)sum= 15/2(1+29)
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n30= 2n15= nalso, sum =n/2(a+l)sum= 15/2(1+29)sum=15/2(30)
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n30= 2n15= nalso, sum =n/2(a+l)sum= 15/2(1+29)sum=15/2(30)sum=15*15
1,3,5,........29.a=1d=3-1=2also, l=a+(n-1)dl=1+(n-1)229=1+2n-229= -1+2n30= 2n15= nalso, sum =n/2(a+l)sum= 15/2(1+29)sum=15/2(30)sum=15*15sum=225
