Answer:
2
Step-by-step explanation:
the one which is near to x
7,21,27,81,87, 261, 267....
All odd number series from the given figure is
7, 21, 27, 81 , 87....
We can write this series as
7, 7 x 3 , (7x3)+6, ((7x3)+6)x3, (((7x3)+6)x3)+6....
7, 21, 21+6 , 27 x 3, 81+6...
Now, the next term of the series will be
=((((7x3)+6)x3)+6) x 3
= 87 x 3
= 261
And another term of the series will be
= 261 +6
= 267
4.38, 4.397, 4.4 is the order from least to greatest.
Hope everything is clear.
