Answers with Explanation:-
1.       A
        Explanation:
        Each number is twice the preceding one with 1 added or subtracted alternatively.
        So, the next number is (2 x 261 + 1) = 523.
2.       B
        Explanation:
        There are two series (10, 13, 16, 19) and (5, 10, 20, 40), one increasing by 3 and the other multiplied by 2.
3.       C
        Explanation:
        Numbers are 1^2, 2^2, 3^2, 4^2, 5^2, 6^2, 7^2.
        So, the next number is 8^2 = 64.
4.       B
        Explanation:
        Go on multiplying the given numbers by 2, 3, 4, 5, 6.
        So, the correct next number is 1440.
