The common difference is -6.
Because,
14 - 6 = 8
8 - 6 = 2
2 - 6 = -4
-4 - 6 =-10
The next three terms of -243, 81, -27, 9 is
The given series is geometric series
<u>Solution:</u>
Given, series is -243, 81, -27, 9, …
We have to find the next three terms of the above given series.
Now, the given series can also be written as

We can say that, above series is in Geometric Progression with first term = -243 and common ratio = 
Then, next three term would be,

Hence, the next three terms of given G.P series are
