Question

52 , ? , 105, 149 , 206, 277

Answer 1

52+21=73 curect answer

Answer 2

Answer:

73 is the missing number.

Step-by-step explanation:

We will start by finding the difference among the consecutive terms.

$277-206=71\\206-149=57\\149-105=44$

We observe that the difference among the differences increases by 1.

$71-57=14\\57-44=13$

Thus the difference in previous term will decrease by 1,

i.e difference will be $44-12=32$

Number will be: $105-32=73$
