Try it... 10, 9, 60, 90, 70, 66, ? 1) 88 2) 96 3) 85 4) 91
Answer (1)
To solve the sequence problem 10, 9, 60, 90, 70, 66, ?, we need to identify the pattern or rule that governs the sequence. In this case, we are dealing with a number puzzle that involves alternating operations.
Let's analyze it step-by-step:
10 and 9 : If we notice the transition between these two numbers, it looks like simple subtraction: 10 - 1 = 9.
9 and 60 : This is a bit less straightforward. However, if you think of multiplying, you could say: 9 * 6 + 6 = 60.
60 and 90 : Another jump, but could fit a pattern of addition: 60 + 30 = 90.
90 and 70 : Here, a subtraction pattern could be seen: 90 - 20 = 70.
70 and 66 : We subtract again: 70 - 4 = 66.
Now, let's figure out what comes after 66 by considering consistent operations that fit the previous logic.
Based on the established alternating pattern (subtraction, multiplication and addition, subtraction, subtraction, subtraction):
If the next operation follows the pattern of multiplication like the shift from 9 to 60 (i.e., multiplying and some addition), the next operation could be:
66 * 1 + 25 = 91.
So, the Sequence: 10, 9, 60, 90, 70, 66, should follow with 91.
Therefore, the answer to the sequence puzzle is option 4), 91.
