Um we need to see the diagram in order to answer this question sorry...but have a good day :)
The answer is d)3 because each number gets multiplied by 3 to qual the next number
The answer is 23 because you would substitute in the 4 for the X and multiply 5 times 4 = 20 then add 20 plus 3 and you get 23
Answer:
3.5 times 2 equals 7 so try 2.5 times 2 which would be 5, 5 could be the answer but im not sure :)
