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?
You first can notice that the x number is 5/2 times bigger then the x+2 number(x is a number in the sequence).
Hoped my "hint" helped.
Or just do the math until you got the 10th number.
