Correct! @Mayank_Chowdhary

#7

Did u get first one bro ?

#8

@Mayank_Chowdhary @Tushar_Rathore
Why do we want the series to be repeating. Not getting this part?

#9

Nope trying
Just solved till here
513=a+2b+3c+4d
4745=a+16b+81c+256d
and we need to find min of (a+4b+9c+16d)
Had the series not been repeating then we would at some point get a fraction
If we had a increasing or decreasing series we would at some point get a fraction @Viraam_Rao

#10

Bro, why does a,b,c,d have to be the same for S1 and S4.
Like can't
4745 = h + 15 f + 81 g + 256 m

#11

a_i would be fixed right ?

Because the order of the a's doesn't matter, we simply need to find the number of 1s 2s 3s and 4s that minimize S_2.
