Q. Type the missing number in this sequence:\newline75,  73,  71,  ____,  67,  65,  6375,\;73,\;71,\;\_\_\_\_,\;67,\;65,\;63
  1. Identify Pattern: Step 11: Identify the pattern in the sequence.\newlineThe sequence decreases by 22 each time: 75−73=275 - 73 = 2, 73−71=273 - 71 = 2.
  2. Apply Pattern: Step 22: Apply the pattern to find the missing number. 71−2=6971 - 2 = 69.
  3. Check Sequence: Step 33: Check the sequence with the filled number. 75,73,71,69,67,65,6375, 73, 71, 69, 67, 65, 63. Each step decreases by 22, confirming the pattern is consistent.
