Q. Find the 14 th term of the arithmetic sequence −5x+1,−12x−3,−19x−7,…Answer:
Find Common Difference: To find the 14th term of an arithmetic sequence, we need to determine the common difference between consecutive terms and then use the formula for the nth term of an arithmetic sequence, which is an=a1+(n−1)d, where an is the nth term, a1 is the first term, n is the term number, and d is the common difference.First, let's find the common difference (d) by subtracting the first term from the second term.d=(−12x−3)−(−5x+1)nth0nth1
Calculate 14th Term: Now that we have the common difference, we can use the formula to find the 14th term a14.a14=a1+(14−1)(−7x−4)a14=(−5x+1)+13(−7x−4)
Simplify Expression: Next, we will simplify the expression to find a14. a14=(−5x+1)+(−91x−52)a14=−5x+1−91x−52a14=−96x−51
