well if it asks you to send to 4 people and there are 8 generations which includes yours that mean
1 sent to 4 - 4 recived
4 send to 4 each = 16 recived + the 4 before = 20 (generation 2)
16 send to 4 = 64 + 20 = 84 (generation 3)
64 send to 4 = 256 + 84= 320 (g4)
256 send to 4 = 1024 + 320 = 1344 (g5)
1344 s t 4 = 5376 + 1344= 6730 (g6)
so on and so forth till generation 8
Answer:
Total number of emails send after 8 email generation is given as
4+16+64+256+1024+4096+16384+65536=87380
Number of email received after 8 email generation is given as
1+4+16+64+256+1024+4096+16384=21845
Step-by-step explanation:
In this question it is given that First email is send to four peoples
Therefore in generation-1
Number of email received=1
Number of email sent by first person=[tex]4[/tex]
generation-2
Number of email send by 4 persons if each send 4 email[tex]=4\times4=16[/tex]
generation-3
Number of email send by 16 persons if each send 4 email[tex]=16\times4=64[/tex]
generation-4
Number of email send by 64 persons if each send 4 email[tex]=64\times4=256[/tex]
generation-5
Number of email send by 256 persons if each send 4 email=[tex]256\times4=1024[/tex]
generation-6
Number of email send by 1024 persons if each send 4 email[tex]=1024\times4=4096[/tex]
generation-7
Number of email send by 4096 persons if each send 4 email[tex]=4096\times4=16384[/tex]
Generation-8
Number of email send by 16384 persons if each send 4 email[tex]=16384\times4=65536[/tex]
therefore, Total number of emails send after 8 email generation is given as
[tex]4+16+64+256+1024+4096+16384+65536=87380[/tex]
Number of email received after 8 email generation is given as
[tex]1+4+16+64+256+1024+4096+16384=21845[/tex]
