Step-by-step explanation:
Answer:
242/48
Step-by-step explanation:
1. We may simplify the given extended ratio by dividing the numbers with their GCF. The GCF of the given is 2. Thus, the simplified form is,
2: 11: 15
2. The given sequence is a geometric sequence with a common ratio of 1/3. Therefore, following the number 18 is number 6.
