What comes next? 3, 8, 18, 35, 61, ?
A88
B98
C97
D100
Answer:
B. 98
Read Explanation:
Look at the differences between consecutive terms:
(8 - 3 = 5)
(18 - 8 = 10)
(35 - 18 = 17)
(61 - 35 = 26)
The differences are:
5, 10, 17, 26
Now find the differences between these:
(10 - 5 = 5)
(17 - 10 = 7)
(26 - 17 = 9)
These increase by 2 each time: 5, 7, 9, so the next one should be 11.
Therefore, the next main difference is:
(26 + 11 = 37)
So the next term is:
(61 + 37 = 98)
Answer: 98
