Step Stairs Gap Between Totals
so its has 2 differences
i have to found nth term and also show working
so can i give some solution or answer please
You should be able to recognise that sequence. At least make some attempts - look at the differences between each one, for example.
I'll tell you that the nth term is n(n+1) / 2 because that will get you very few marks. See if you can work out why (think about the name given to this sequence).
Though I might have slightly misunderstood you ("2 differences"?); if so, I apologise.
its quadretic sequence
but i didnt get it
