Answer:
WHAT IS YOUR QUESTION
Step-by-step explanation:
You've given us a single term of an arithmetic series. So far, there are an infinite number of different series that it could be a member of. ... In fact, ANY function f (n) for which f (7) = 54 produces a suitable series for whole-number values of 'n'. Here are a few: ... T(n) = n + 47. ... T (n) = 8n - 2. ... T (n) = -10n + 124 .
You can add 14 to the 9 to get pith of the problem so you'd be left with |2x+1| = 23 then it comes it quite obvious that X=11 because 2 times 11 plus 1 equals 23
