Answer 1

What is the missing number of the following sequence - 5319, 73, 5339, 7386, 86, 7406, ?, 57, 3259

First and third number are square of middle number-10 and +10 respectively....

73^2=5329
5329-10=5319
5329+10=5339 so series is 5319,73,5339

next , 86^2=7396
series is (7396-10) , 7396 , ( 7396+10) = 7386,7396,7406

next
57^2=3249
so series (3249-10) , 3249 , (3249+10) =3239,3249,3259
answer is 3239
