What is the recursive rule for the sequence? −7.4, −21.2, −35, −48.8, −62.6

Step-by-step explanation:

The recursive rule for the arithmetic sequence is given by:

         .....[1]

where, d is the common difference of two consecutive terms.

Given the sequence:

−7.4, −21.2, −35, −48.8, −62.6

This is an arithmetic sequence

Here, first term = -7.4 and d = -13.8

Since,

-21.2+7.4 = -13.8,

-35+21.2 = -13.8 ans so on...

Substitute the given value in [1] we have;

⇒

Therefore, the recursive rule for the sequence is, and = -7.4
