Answer 1

Answer:

First term is 51.

Second term be x.

Third term is 81.

Fourth term is 108.

On solving:-

\begin{gathered} = > 51 : x :: 81 : 108 \\ = > \frac{51}{x} = \frac{81}{108} \\ = > x = \frac{108 \times 51}{81} \\ = > x = \frac{108 \times \cancel51}{ \cancel81} \\ = > x = \frac{108 \times 17}{27} \\ = > x = \frac{ \cancel108 \times 17}{ \cancel27} \\ = > x = 4 \times 17 \\ = > \boxed{x = 68}\end{gathered}
