Q. The first three terms of a sequence are given. Write your answer as a decimal or whole number. Round to the nearest thousandth (if necessary).\newline460,451,442, 460,451,442, \ldots \newlineFind the 4646th term.\newlineAnswer:
  1. Determine common difference: First, we need to determine the common difference in the sequence by subtracting the second term from the first term.\newline460451=9460 - 451 = 9
  2. Verify consistency: Now, we subtract the third term from the second term to verify that the common difference is consistent. 451442=9451 - 442 = 9
  3. Confirm arithmetic sequence: Since the common difference is consistent, we can confirm that this is an arithmetic sequence with a common difference of 99.
  4. Use nth term formula: To find the 46th46^{\text{th}} term, we use the formula for the nth term of an arithmetic sequence: an=a1+(n1)da_n = a_1 + (n - 1)d, where ana_n is the nth term, a1a_1 is the first term, nn is the term number, and dd is the common difference.
  5. Plug in values: We plug in the values we know into the formula: a46=460+(461)(9)a_{46} = 460 + (46 - 1)(-9), since the sequence is decreasing, the common difference is negative.
  6. Calculate parentheses: Now we calculate the value inside the parentheses: 461=4546 - 1 = 45.
  7. Multiply common difference: Next, we multiply the common difference by 4545: 45×(9)=40545 \times (-9) = -405.
  8. Add to find 4646th term: Finally, we add this value to the first term to find the 4646th term: 460+(405)=55460 + (-405) = 55.
  9. Final result: The 46th46^{\text{th}} term of the sequence is 5555, which is a whole number and does not need to be rounded.
