Answer:
The original amount is always 100% at the start.
Adding 100% will make the amount 200%, which is double the original amount.
Adding 200% will make the amount 300%, which is triple the original amount.
now, let's recall that a geometric sequence is one that uses some "r" common ratio to get the next term, by simply multiplying the current term by it.
and of course, the next term or a₅ = 54(3) --> a₅ = 162.
This sequence of numbers works because each time it is multiplied by 2.
(2x2=4 4x2=8 8x2=16) etc...
In conclusion each number is multiplied by 2 in the sequence.
(16, 40). That’s because it does not repeat a number. hope this helps!
