Hey ... M afraid not! The OA is 3756theCodeToGMAT wrote:5, 16, 60, 236, 940,
16-5 = 11
60-16 = 44 = 11x4
236-60 = 176 = 44x4
940-236 = 704 = 174*4
So, next digit = 236 + 704*4 = 3052
Is it correct?

Let initial diameter = d1, final diameter = d2 Initial area = ((pi)d1^2)/4 Final area = ((pi)d2^2)/4 Final area = initial area + (800/100 * initial area) = 9*initial area = 9*((pi)d1^2)/4 Equate the above 2 final areas. ((pi)d2^2)/4 = 9*((pi)d1^2)/4 d2 = 3*d1 % increase = ((d2 - d1)*100)/d1 = ((...
