Find the 60th term of the arithmetic sequence <br> −29,−49,−69,...
Mariulka [41]

Answer:

  -1209

Step-by-step explanation:

Your sequence has first term a1 = -29 and common difference d = -20. Using these in the formula for the n-th term, we can find the 60 term.

  an = a1 +d(n -1)

  an = -29 -20(d -1)

  a60 = -29 -20(60 -1) = -1209
