Rita spent 20$. By multiplying 5 pairs with 4$ we can see that it will equal 20$
A bc to find the ratio u have to divide them for how much 1 would be
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
Only two triangles:
The 90* angle is stable, so you can change only the position of the 50* and 40* angles.
1 triangle: 40* is right to the 90*
2 triangle: 40* is left to the 90*
Hope this helped you!
