Answer:
2, 5, 11, 23, 47, 95, 191
A, Z, B, Y, C, X, D, W, E, V
Step-by-step explanation:
1. 2, 5, 11, 23, 47, ...95, 191
5 - 2 = 3
12 - 5 = 6
23 - 11 = 12
47 - 23 = 24
Next
(24 × 2) + 47
= 48 + 47
= 95
Next
(48 × 2) + 95
96 + 95
= 191
Next
(96×2) + 191
192 + 191
= 383
The pattern follows (difference ×2) + previous number
That is,
(5 - 2) * 2 + 5
3*2 + 5
6 + 5
= 11
2, 5, 11, 23, 47, 95, 191
2. A, Z, B, Y, C, ...
First letter , 26th letter, 2nd letter, 25th letter, 3rd letter, 24th letter, 4th letter, 23rd letter, 5th letter, 22nd letter
A, Z, B, Y, C, X, D, W, E, V
