Math Problem Statement

6. Find the missing number in the sequence: 22, 24, 28, ?, 52, 84. 7. Find the missing number in the sequence: 0, 2, 8, 14, ?, 34.

Solution

Let us solve the missing terms in the sequences provided:

Question 6: Sequence - 22,24,28,?,52,8422, 24, 28, ?, 52, 84

  • Pattern Observation: The difference between consecutive terms is as follows:
    • 2422=224 - 22 = 2
    • 2824=428 - 24 = 4
    • Missing number difference should be 66, leading to:
      • 28+6=3428 + 6 = 34
    • Next differences: 5234=1852 - 34 = 18 and 8452=3284 - 52 = 32, verifying the sequence.

Answer for Question 6: ?=34? = 34


Question 7: Sequence - 0,2,8,14,?,340, 2, 8, 14, ?, 34

  • Pattern Observation: The difference between consecutive terms is as follows:
    • 20=22 - 0 = 2
    • 82=68 - 2 = 6
    • 148=614 - 8 = 6
    • The differences seem to alternate between +2,+6,+6+2, +6, +6, suggesting the next is +6+6, leading to:
      • 14+6=2014 + 6 = 20

Answer for Question 7: ?=20? = 20

Related Questions:

  1. Can you identify similar number patterns with increasing or alternating differences?
  2. How would you determine missing terms if the pattern was multiplication or division instead of addition?
  3. What strategies help in recognizing complex sequences, like Fibonacci or geometric progressions?
  4. Can you create your own sequence and challenge the logic behind it?
  5. How do alternating patterns behave in real-world problem-solving situations?

Tip: Always write down the differences or ratios between consecutive terms to identify hidden patterns quickly.
