forget tat.. jus take the simple general formula as an^2+bn+c
now extrapolate to find the zeroth term of the sequence.. it is 1
if n=0; the equation becomes a(0)+b(0)+c=1; therefore c=1
if n=1; the first term of the sequence is actually 1, so a(1)+b(1)+c=1 and as we know tat c=1, a+b has...

wat if the sequence is like this, 3,5,9,15,23.... upto 2000 nos...
the formula will change uh

guys can u pls tel me how to proceed with these sort of probs in which the intervals of the sequences are in a.p
find the sum of the series.. 1,2,4,7,11,16 ...... for 2000 terms
