Math Problem Statement

10th term: a1 = 32, d = - 6

Solution

To find the 10th term of an arithmetic sequence where the first term a1=32a_1 = 32 and the common difference d=6d = -6, we can use the formula for the nnth term:

an=a1+(n1)×da_n = a_1 + (n - 1) \times d

Step 1: Identify the values

  • a1=32a_1 = 32
  • d=6d = -6
  • n=10n = 10

Step 2: Substitute the values into the formula

a10=32+(101)×(6)a_{10} = 32 + (10 - 1) \times (-6) a10=32+9×(6)a_{10} = 32 + 9 \times (-6) a10=3254a_{10} = 32 - 54 a10=22a_{10} = -22

Final Answer

The 10th term of the sequence is 22-22.

Tip: When working with negative common differences, remember that the sequence decreases over time.
