Answer:
28
Step-by-step explanation:
Let n = 21, and evaluate the expression.
![a_n = -2 + \dfrac{3}{2}(n - 1)](https://tex.z-dn.net/?f=%20a_n%20%3D%20-2%20%2B%20%5Cdfrac%7B3%7D%7B2%7D%28n%20-%201%29%20)
![a_{21} = -2 + \dfrac{3}{2}(21 - 1)](https://tex.z-dn.net/?f=%20a_%7B21%7D%20%3D%20-2%20%2B%20%5Cdfrac%7B3%7D%7B2%7D%2821%20-%201%29%20)
