Let k = the constant amount added to the sequence since this
is an arithmetic sequence
x = missing
number
You have to formulate an equation based on the sequence:
6 + k = x or k = x – 6
x + k = 30
Substitute the value of k to the second formula:
x + x – 6 = 30
2x = 36
x = 18
Therefore, the missing number is 18.
B
42 times 25.5=1071
771.1/1071= 0.72

Answer:
when I worked it out I actually got -1466...
Step-by-step explanation:
Using order of operations you would multiply the 2 by 742, then subtract from left to right. 2 x 742 =1484 and 30 minus that is -1454. Subtracting 12 would give you -1466. I know that's not in the answer choices but that's what I got...
I'm pretty sure this is correct, but it depends on how ur teacher wants it to be written like.
