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

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :
