Question

Any help? I'm having trouble finding the 0th and 15th terms for this geometric sequence.

Answer 1

0th term

`T_0=(4)/(27)andthe15thterm=T_(15)=19,131,876_{}^{}`

By formula, the nth term of a G.P. is given by,

`\begin{gathered} T_n=ar^(n-1),where,r=(T_2)/(T_1)_{}=(T_3)/(T_2)=(12)/(4)=(36)/(12)=3 \\ \end{gathered}`
