Answer:
15
Step-by-step explanation:
the pattern is like this
start with 1 then add 2 equals 3
start with 3 then add 3 equals 6
so 6 add 4 equals to 10
and the 5th term will be 10 add 5
equals to 15
12 goes into 276 23 times.
= 12 + (- 6)(n - 1 )
This is an arithmetic sequence with n th term
= 
+ (n - 1)d
here d = - 6 - 0 = 0 - 6 = 6 - 12 = -6 and = 12, hence
= 12 + (- 6)(n - 1)
use this formula to find the 30 th term
= 12 + (- 6 × 29) = 12 - 174 = - 162
-2x-11 is equivalent to 3x-4-(5x+7)
The best answer for the question of what illustrates the commutative property of addition is letter c which is 22 + 11 = 11 + 22. Because the commutative property of addition states that a + b = b + a, thus the chosen answer is the best answer.
