Solution: The commutative property of addition states that when two numbers are being added, their order can be changed without affecting the sum.
Answer:
I would say soild 2 because is has the most even ammount of the 4.
How I understand from your writing next term is equal previous plus 3,
if 1st is -4, then next (second) should be -4+3= -1
To find this out the easy way, add up all the numbers and an answer, then divide by 4.
59 + 64 + 68 + 63.67 = 254.67
254.67/4 = 63.66
A is not correct.
59 + 64 + 68 + 65.25 = 256.25
256.25/4 = 69.25
B is not quite correct.
59 + 64 + 68 + 75 = 266.
266/4 = 66.5
C is not correct.
59 + 64 + 68 + 89 = 280
280/4 = 70.
D.) is the correct answer.
I hope this helps!
