1d no of terms are like this
1+2+3+4...n
n(n+1)/2≤1000
n(n+1)≤2000
on solving this i think u get 45
1A das gupta question had done 2 years back :D :P
they hav given d solution also
1If u go on with the progression with 1,2,2,3,3,3,4,4,4,4........ then its coming 45
If u solve it u will get that 1000≥n(n+1)/2
=2000≥n(n+1)/2 and thereby going u are getting 45
