What is the 15th term in the arithmetic sequence described by this explicit formula? an = 63 + (n – 1)(–7)

= -35.

Step-by-step explanation:

Given :   = 63 + (n – 1)(–7)

To find : What is the 15th term in the arithmetic sequence .

Solution : We have given   = 63 + (n – 1)(–7).

We need to find 15 th terms  ,  n = 15

= 63 + (15 – 1)(–7).

= 63 + 14 (-7).

= 63 -98.

= -35.

Therefore,   = -35.
