Q. 25=2+15(n−1)25=2+15(n-1) solve for nn
  1. Distribute and Simplify: Simplify the right side of the equation by distributing 1515 into (n−1)(n-1). \newline25=2+15n−1525 = 2 + 15n - 15\newlineCombine like terms on the right.\newline25=15n−1325 = 15n - 13
  2. Combine Like Terms: Isolate the variable term 15n15n by adding 1313 to both sides.\newline25+13=15n25 + 13 = 15n\newline38=15n38 = 15n
  3. Isolate Variable Term: Solve for nn by dividing both sides by 1515.n=3815n = \frac{38}{15}n=2.5333n = 2.5333
