Iionel finished four rounds of a golf tournament . his combined total score after playing all four rounds was -10. his scores on the first three rounds were -4, -2, and -6. what was his score on the lasr round? justify your answer

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
