Answer:
Find out the what is the eighth term in the arithmetic sequence defined by the explicit formula.
[tex]a_{n} = 2n + 7[/tex]
To prove
As given the explicit formula for the arithmetic sequence .
[tex]a_{n} = 2n + 7[/tex]
Put n = 8
[tex]a_{8} = 2\times 8 + 7[/tex]
[tex]a_{8} = 16 + 7[/tex]
[tex]a_{8} = 23[/tex]
Therefore the eighth term in the arithmetic sequence is 23 .
The answer is 23.
an=2n+7 >>>>> 2*8= 16 >>> 16+7=23
There eighth term will be 23.
