Answer 1

Step-by-step explanation:

10      17          31         ?            115          277

    7         14          28        56           112

31 + 28 = 59

? = 59          

Answer 2

Concept:

When sequence follow a particular pattern, it becomes a series.

Given:

We are given the series:

10, 17, 31, ?, 115, 277

Find:

We need to find the missing number.

Solution:

Let the missing number be x.

So, the series become:

10      17          31         x            115          277

Now we can see that the difference between the each number in the series has a pattern that is:

17 - 10 = 7

31 - 17 = 14

277 - 115 = 162

So, the difference is increasing by 2 times in the pattern.

So, x should be:

x - 31 = 28

x = 31 + 28

x = 59

This will complete the pattern as:

17 - 10 = 7

31 - 17 = 14

59 - 31 = 28

115 - 59 = 56

277 - 115 = 162

Therefore the missing number is 59.
