We can observe that for every serving, the number of crackers is increasing by 6. So, for $x$ servings, the number of crackers can be found by the formula $6x$.
Therefore, if we want to find the number of servings for 42 crackers, we can set up the equation $6x = 42$.
Simplifying the equation, we find that $x = \boxed{7}$ servings.
There are 6 crackers for 1 serving, 12 crackers for 2 servings, 18 crackers for 3 servings and so on. How many servings for 42 crackers?(1 point)
