From the first term to the second, divide by (2/1) squared.

From the second to the third, divide by (3/2) squared.

From the third to the fourth, divide by (4/3) squared

Dividing 62.5 by (5/4)squared yields 40.

Chris
think its 40 as its a twentyfith of 1000. after 1000 the numbers are 1000 divided by squares , ie 1(1), 2(4),3(9),5(25)
