-7 and +1
6/7 × 7/11 = (6×7)/(11×11) = 42/121
The two numbers that add up to -6 and multiply to -7 are -1 and 7. This is because -1 + 7 = -6 and -1 * 7 = -7. These numbers satisfy both conditions given in the question.
The two numbers that add up to 7 and multiply to 8 are 1 and 6. When you add them together, 1 + 6 equals 7, and when you multiply them, 1 × 6 equals 6. However, the correct pair that meets both criteria is 2 and 4; they add up to 6 and multiply to 8. Therefore, the answer is 1 and 6.

In the sequence 20 5 30 6 42 7, the rule is divide by 4 then multiply by 6, divide by 5 then multiply by 7, divide by 6 then multiply by 8 since each time the number by which you multiply or divide by increases by 1. Since the last multiplication was by 7, we know the next will be by 8. Therefore, the answer you get for the next number in the sequence is 56 (7x8=56).
