Answer:
-34.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 and common difference -2.
nth term = a1 + d(n - 1)
23rd term = 10 - 2(23-1)
= 10 - 44
= -34.
Answer:
-34
Step-by-step explanation:
The sequence starts with 10. Each subsequent term is 2 less than the previous term.
The common difference is -2.
The second term is 10 + (-2) × 1
The third term is 10 + (-2) × 2
The fourth term is 10 + (-2) × 3
Each term you subtract a multiple of -2 from 10. The multiple is 1 less than the number of the term multiplied by -2.
For term n, you get 10 + (-2) × (n - 1).
The 23rd term is:
10 + (-2) × (23 - 1) = 10 - 2 × 22 = 10 - 44 = -34
