The answer is (9+3)6

There are two ways to solve:
1. Using the Distributive Property
(9 + 3) 6
=(54 + 18)
=72

2. Adding what is in the parentheses first
(9 + 3) 6
=(12) 6
=72

This is the associative property. Basically if you move the parenthesis either to left or right you’ll still get the right answer. So 4 times 5 equals 20 and 20 times 3 equals 60. 3 x 4 equals 12 and 12 x 5 equals 60

Recursive formula for 26, 24, 22, 20

dexar [7]

Answer:

a_n = 28-2n

Step-by-step explanation:

Given sequence is:

26,24,22,20

We can see that the difference between consecutive terms is same so the sequence is an arithmetic sequence

The standard formula for arithmetic sequence is:

$a_n = a_1+(n-1)d$

Here,

a_n is the nth term

a_1 is the first term

and d is the common difference

So,

d = 24-26

= -2

a_1 = 26

Putting the values of d and a_1

$a_n = 26 + (n-1)(-2)\\a_n = 26-2n+2\\a_n = 28-2n$

Hence, the recursive formula for given sequence is: a_n = 28-2n ..
