Question

Find the 35th term in the arithmetic sequence: -10, -14, -18, -22,...

Answer 1

Step-by-step explanation:

-10, -14, -18, -22,...

$a1 = - 10 \\ a2 = - 14 \\ d = a2 - a1 \\ d = - 14 - - 10 \\ d = - 14 + 10 = - 4 \\ an = a1 + (n - 1)d \\ a35 = - 10 + (35 - 1) \times ( - 4) \\ a35 = - 10 + 136 \\ a35 = 126$
