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
