First, you should remember the table of multiply of 7.. we gonna do it...
[tex]\begin{gathered} 7x1=7 \\ 7x2=14 \\ 7x3=21 \\ 7x4=28 \\ 7x5=35 \\ 7x6=42 \\ 7x7=49 \\ 7x8=56 \\ 7x9=63 \\ 7x10=70 \end{gathered}[/tex]
You can note that the first number correspond to 7 x 1 = 7
the second number correspond to 7x3=21
the thrid number will be 7x4=28
and the latest number of the first part will be 7x6=42
For the second part we deduce the same fron table of 6... we do it quickly..
[tex]\begin{gathered} 6x1=6 \\ 6x2=12 \\ 6x3=18 \\ 6x4=24 \\ 6x5=30 \\ 6x6=36 \\ 6x7=42 \\ 6x8=48 \\ 6x9=54 \\ 6x10=60 \end{gathered}[/tex]
From that table, the first value is 6, later the first gape or second value will be 12
I need make a correction, the relationship to find the gaps will be determined comparing that two tables of multiply.. table of 7 and table of 6.... then..
From that image you have the first group of values...
And from that image you have the latest values to complete the gaps..
