Answer 2

Answer: The correct answer is 13

Step-by-step explanation:

• The given sequence is 27, 25, 25, 22, 23, 19, 21, 16, 19, ?
• Take first 2 elements from sequence, add them up 52, divide by 2 gives nearest gives 25
• Now take 2nd and 3rd element 25 and 25 there average gives 25, subtract with 3 we get 22
• Now take 3rd and 4th element 25 and 22 there average to nearest value is 23
• Now our 4th and 5th values are 22 and 23 , there nearest average is 23, subtract it with 4, we get 19
• Now 5th and 6th elements are 23 and 19, There nearest average is 21
• Now our 6th and 7th elements are 19 and 21. The nearest average is 20. subtract with 4 we get 16
• Now our 7th and 8th elements are 21 and 16. The nearest average is 19
• Now our 8th and 9th elements are 16 and 19. There nearest average is 17. Subtract with 4 we get 13.
• every 4th number should be even in the series
• each average should be odd number but expect for the 4th number ones.
