Explanation

The pattern is:

• $5 times 2 + 1 = 11$
• $11\times 2+1=23$
• $23\times 2+1=47$
• $47\times 2+1=95$

Answer: 95

Explanation

The pattern is:

1×2+1=3

3×2+1=7

7×2+1=15

15×2+1=31

31×2+1=63

So,

63×2+1=127

Explanation

Find the difference between terms:  

10 - 2 = 8  

20 - 10 = 10  

38 - 20 = 18  

64 - 38 = 26  

Differences: 8, 10, 18, 26  

Now find difference of differences:  

10 - 8 = 2  

18 - 10 = 8  

26 - 18 = 8  

Next difference increases by 8 again  

So next difference = 26 + 8 = 34  

Next term = 64 + 34 = 98

Explanation

The differences are increasing by 2:

6 → 11 (+5)

11 → 18 (+7)

18 → 27 (+9)

So the missing number is 18.

Explanation

Look at the pattern: each term × 3  

2 → 6 → 18 → ? → ? → 486  

So 18 × 3 = 54

54 × 3 = 162  

162 × 3 = 486  

Full sequence: 2, 6, 18, 54, 162, 486  

Now "4th term from the last"  

Last = 486, 2nd last = 162, 3rd last = 54, 4th last = 18.
