the first term in this number pattern is 7. 7, 12, 10, 15, 13, ... what is the eighth term in this pattern? type the number in the box.
Answer
Explanation:
Step1: Analyze the pattern
The pattern has two - sub - patterns. The odd - numbered terms (1st, 3rd, 5th, ...) increase by 3: (7+3 = 10), (10+3=13). The even - numbered terms (2nd, 4th, ...) increase by 3: (12 + 3=15).
Step2: Determine the 8th term
Since 8 is an even - numbered term. The 2nd term is 12, the 4th term is 15, the 6th term is (15 + 3=18), and the 8th term is (18+3 = 21).
Answer:
21
