Let's call the number "n"
if we write in an equation what you said it's like this:
n*2+4-n-3=n+1.
first i will move all the "n"s to the left and all the numbers to the right
n*2-n-n=1+3-4
which is....
0=0
this means that for EVERY number, if you double it, add four, subtract three, you will get this number plus one. <span />
Answer: the answer is the first one ,the third one , and the fourth

"Correlation does not imply causation<span>" is a phrase used in </span>statistics<span> to emphasize that a </span>correlation<span> between two variables does not imply that one </span>causes the other. Correlation is the relationship between two sets of variables used to describe or predict information. Causation<span>, also known as cause and effect, is when an observed event or action appears to have caused a second event or action.
Hope this helps. :)</span>
