Answer:
5th term is 9, 30, and -20.3 and the 23rd term is 45, 174, and -132.9
Explanation:
The given pattern consists of three mathematical expressions: 2x + 1, 8x - 2, and -6.2x + 4.5. To find the 5th and 23rd term of the pattern, we need to substitute x with the corresponding value and evaluate the expressions for each of the terms.
For the 5th term:
x = 5-1 = 4
So, the 5th term would be:
2x + 1 = 2 * 4 + 1 = 9
8x - 2 = 8 * 4 - 2 = 30
-6.2x + 4.5 = -6.2 * 4 + 4.5 = -24.8 + 4.5 = -20.3
For the 23rd term:
x = 23-1 = 22
So, the 23rd term would be:
2x + 1 = 2 * 22 + 1 = 45
8x - 2 = 8 * 22 - 2 = 174
-6.2x + 4.5 = -6.2 * 22 + 4.5 = -136.4 + 4.5 = -132.9
Therefore, the 5th term is 9, 30, and -20.3 and the 23rd term is 45, 174, and -132.9 for the given pattern of mathematical expressions.
