Final answer:
The arithmetic function for the given sequence is nth term = -10 + (n-1) × (-2). Using this function, we can find the first ten terms of the sequence.
Step-by-step explanation:
An arithmetic sequence is a sequence of numbers in which the difference between consecutive terms is constant.
For this scenario, the first term is -10 and the common difference is -2.
To find the arithmetic function for this sequence, we can use the formula:
nth term = first term + (n-1) × common difference
Plugging in the values, we have:
nth term = -10 + (n-1) × (-2)
Using this function, we can find the first ten terms of the sequence as follows:
- n = 1: nth term = -10 + (1-1) × (-2) = -10
- n = 2: nth term = -10 + (2-1) × (-2) = -12
- n = 3: nth term = -10 + (3-1) × (-2) = -14
- n = 4: nth term = -10 + (4-1) × (-2) = -16
- n = 5: nth term = -10 + (5-1) × (-2) = -18
- n = 6: nth term = -10 + (6-1) × (-2) = -20
- n = 7: nth term = -10 + (7-1) × (-2) = -22
- n = 8: nth term = -10 + (8-1) × (-2) = -24
- n = 9: nth term = -10 + (9-1) × (-2) = -26
- n = 10: nth term = -10 + (10-1) × (-2) = -28
