## Solution - Challenge 68 - Generate a Particular Sequence

By |Tuesday, January 16th, 2018|Categories: Solutions||0 Comments

Below is a possible solution to the problem Challenge 67 - Generate a Particular Sequence -

This consists of 2 logic.

1. Generate Triangular number. The formula for which is n*(n+1)/2
2. Generate Column Labels (A, B, AA, ZZ....) from numbers, the formula for which is

=SUBSTITUTE(ADDRESS(1,3,4),1,"") where 3 is for column C. So, we need to vary this 3.

The combined formula would be -

=SUBSTITUTE(ADDRESS(1,(ROW(1:1)-1)*ROW(1:1)/2+1,4),1,"")

This time challenge before you is to write a formula which can be dragged down and leaves so many blank cells - 1 before that alphabet's position in English Language. Hence, the sequence will start with A, will leave 1 blank cell, then B, then 2 blank cells, then C, then 3 blank cells, then D, then 4 blank cells, then E, then 5 blank cells, then F....................................................................then 24 blank cells, then Y and finally 25 blank cells and then Z.
