Which answer is the explicit rule for the sequence 12.5, 11, 9.5, 8, 6.5, 5  ?

Step-by-step explanation:

The explicit rule for the arithmetic sequence is given by:

         ....[1]

where,

is the first term

d is the common difference and n is the number of terms.

Given sequence:

12.5, 11, 9.5, 8, 6.5, 5 ...

This is an arithmetic sequence.

here,  and d =- 1.5

Substitute these in [1] we have;

⇒

⇒

Therefore, the explicit rule for the given sequence is,
