Anyone know answers ?

1.) On the 5th time they're sent it will have 1364 chain letters

2.) On the 6th time they're sent it will have 5460 chain letters

Step-by-step explanation:

4^x + y (y of x - 1)

4^1 + 0

4 + 0 = 4

4^2 + 4

16 + 4 = 20

4^3 + 20

64 + 20 = 84

4^4 + 84

256 + 84 = 340

4^5 + 340

1024 + 340 = 1364

4^6 + 1364

4096 + 1364 = 5460

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42

b because it contains 40% of the possible results from the random list.  

0,1,2,3 v 4,5,6,7,8,9  

4 integers to 6 integers  

40% success vs 60% fail
