These problems deal with sequences of numbers. Can you spot what the sequences' rules are?
Let the increasing sequence of integers D: d1, d2, d3, ...dn-1, dn... represent the sequence of consecutive differences of another sequence T: t1, t2, t3, ...tn-1, tn.

Given t1=0 , and tk-tk-1=dk-1=k, provide definition and formula for the sequence T.
