Asequence can be defined by the explicit formula an=5-3n which recursive formula represents the same sequence of numbers?

or

Step-by-step explanation:

Consider the sequence formed using rule

You can see that each next term of the sequence is less than previous by 3. Thus, the recursive formula that represents the same sequence of numbers is

or

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
