PLS EXPLAIN HOW THESE SEQUNCE IS FORMED

ALL ODD NUMBERS

7,21,27,81,87, 261, 267

Step-by-step explanation:

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

7,21,27,81,87, 261, 267

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
