Question

Whats the rule for this pattern, 3,1.5,0,-1.5,-3

Answer 1

The pattern subtracts 1.5 for each number in the pattern. 3-1.5 is 1.5. 1.5 minus 1.5 is zero. 0 minus 1.5 is -1.5. -1.5 minus 1.5 is negative 3. If we apply this rule to the next value, it would be -3 minus 1.5 which is equal to 4.5. The value after that would be 6, applying the same rule.
