Answer: 35
Explanation So in this way the next number in the sequence, 0, 3, 8, 15, 24, 35 From the given series the logic is adding odd numbers in the series 0 + 3 = 3 3 + 5 = 8 8 + 7 = 15 15 + 9 = 24 24 + 11 = 35
Answer: 104
Explanation The common difference equals: 16 The sum of the sequence equals: 512 The explicit formula of this sequence is: � � = 8 + ( � − 1 ) ⋅ 16 The recursive formula of this sequence is: � � = � ( � − 1 ) + 16 The nth terms: 8 , 24 , 40 , 56 , 72 , 88 , 104 , 120 ,
Answer: 48
Explanation a = 3, r = 2 5th term: 3, 6, 12, 24, 48
Answer: 91
Explanation The given series is formed by adding 1, 4, 9, 16, 25, and 36 (which are consecutive perfect squares) to the previous term. Breaking it down: 1 + 1 = 2 2 + 4 = 6 6 + 9 = 15 15 + 16 = 31 31 + 25 = 56 56 + 36 = 92 (not 91) So, the correct series would be: 1, 2, 6, 15, 31, 56, 92. Therefore, the wrong number in the series is 91.
