Answer 1

Answer:

answer is 15840

Step-by-step explanation:

there is a difference of cubes in between

start from right end

15757- 15784= -27 = 3^3

15784-15720= 64 = 4^3

15720-15840= -120 ( so generally here it should be 5^3)

15629-15840= 211 (here it should be 6^3)

15629-15972= -343 = 7^3

So the no. 15840 should be changed to 15845

Answer is 15840
