By starting with a million and alternatively dividing by 2 and multiplying by 5, Anisha created a sequence of integers that starts 1000000, 500000, 2500000, 1250000, and so on. What is the tenth term of this sequence?

We will multiply 1000000  by (5/2) four times (to get the 9th term) and then multiply this result by (1/2) to get the tenth term...so....

 

1000000 (5/2)^4 * (1/2)  =

 

500000 * (5/2)^4

 

500000 * (2.5)^4    =      19,531,250
