Answer 3

\[= -6^n * -6^-1 / 7^n\]

\[-\frac{ 1 }{ 6 }(-\frac{ 6 }{ 7 })^n\]

Answer 5

so a = -1/6 and r = -6/7 plug them into a/ 1-r I get -7/78 but it's wrong ?

Answer 6

Remember the exponent is n-1 for geometric; here you have an n exponent... a1 is not -1/6. Plug in n=1 into your expression above for a1.
