Answer:
[tex]a_{200}=418[/tex]
Step-by-step explanation:
The explicit formula for an arithmetic sequence is given by :
[tex]a_n=20+(n-1)2[/tex] ...(1)
We need to find the 200th term of the sequence.
Put n = 200 in equation (1)
[tex]a_{200}=20+(200-1)2\\\\=20+199\times 2\\\\=418[/tex]
So, the 200th term of the sequence is 418.
