What is the eighth term in the arithmetic sequence defined by the explicit formula
an=2n+7?
a8=

Find out the what is the eighth term in the arithmetic sequence defined by the explicit formula.

To prove

As given the explicit formula for the arithmetic sequence .

Put n = 8

Therefore the eighth term in the arithmetic sequence is 23 .

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
