A%5B1%5D+=+6x%2B10+
If you increase x by 2 you get +A%5B2%5D+=+6%28x%2B2%29%2B10+=+%286x%2B12%29%2B10+=+%286x%2B10%29%2B12+=+A%5B1%5D%2B12+.
A increases by 12.
—————————————

An alternate approach is to observe that 6x is the only term that depends on x, so if you increase x by 2 the term 6x increases by 6*2 = 12.
