Let a→,b→\overrightarrow a ,\overrightarrow ba,b and c→\overrightarrow cc be three non-zero vectors such that no two of these are collinear. If the vector a→+2b→\overrightarrow a + 2\overrightarrow ba+2b is collinear with c→\overrightarrow cc and b→+3c→\overrightarrow b + 3\overrightarrow cb+3c is collinear with a→\overrightarrow aa (λ\lambdaλ being some non-zero scalar) then a→+2b→+6c→\overrightarrow a + 2\overrightarrow b + 6\overrightarrow ca+2b+6c equals to :
