Insert The Missing Number : 8, 10, 16, 34, ______________

A: 56
B: 77
C: 88
D: 94

The answer is: C

Explanation

I have realized that the correct answer is indeed C: 88.

The pattern in the sequence is not immediately obvious, but one way to identify it is by looking at the differences between adjacent terms:

10 - 8 = 2

16 - 10 = 6

34 - 16 = 18

Notice that the differences themselves form a sequence: 2, 6, 18. If we continue this pattern by multiplying each difference by 3, we get:

2 x 3 = 6

6 x 3 = 18

18 x 3 = 54

Finally, we can add these differences to the last term in the sequence to get the missing term:

34 + 54 = 88

Therefore, the correct answer is C: 88.
