Question

1722, 995, 508, 213, ______​

Answer 1

Step-by-step explanation:

answer is 62. this is a three tier series

difference between 1722-995 is 727

like. 995- 508 = 487

508-213. = 295

in second tier difference between 727-487=240

487-295=192

then we observed that 240 and 192 are divisible by 12.

12×20= 240. 12×16 =192. we observe that quotient is reduced by 4. so then next series is 12×12=144.

then 144 is subtract from 295 = 151

finally 151 - 213 = 62 ANSWER IS 62
