Answer 1

Answer:

83

Step-by-step explanation:

because see the first number 21 and 35 have a difference of 14.

and then 35 and 41 only 6.

then again it is increased by 4(14+4)=41 and 59 is 18 difference.

then again it is decreased by 4(6-4)=59 and 61 is 2 difference.

next comes +4(18+4)=61 and 83 is 22 difference.
