Question: What's the pattern answer to 7,6,4,6,2,6,1,6, _,6
The answer is 1
Ignore the 6's. They appear at every 2nd entry. Consider them as padding only.
When we remove the sixes, the sequence we are left with is,
7, 4, 2, 1, _
The numbers decrease.
Each decrease is 1 less than the previous decrease.
From 7 to 4, the decrease is 3.
From 4 to 2, the decrease is 2.
From 2 to 1, the decrease is 1.
From 1 to _, the decrease is 0.
i.e. The Underscore, _, = 1
