Question

complete the series 16,3150,77,120

Answer 1

Answer:

I am considering question as 16,31,50,77,120,X

and X is 195.

Step-by-step explanation:

the difference between 31 & 16 is 15,

50-31 = 19,

77-50 = 27,

120-77 = 43,

here,the difference is increasing in the multiples of 4 from 15 as 15,(15+4)19,(19+8)27,(27+16)43&(43+32)75,

so the next number would be 120+75 = 195.

Hope it helps u...
