Find 3 consecutive numbers with a product of (a) −6 (b) 120
(a)
Find 3 consecutive numbers with a product of −6
Answer
The three consecutive numbers are −3, −2, −1.
(b)
Find 3 consecutive numbers with a product of 120
Answer
The three consecutive numbers are 4, 5, 6.
Explanation
(a) Since the product is negative, we need an odd number of negative factors. Checking: (−3) × (−2) × (−1) = −6. (b) Since the product is positive, we can have all positive or all negative factors. Checking: × 6 = 120.
