ANSWER WITH EXPLANATION

1.     (c): The pattern is + 3, +5, +7, +9, So, missing term = 28 + 11 = 39.

2.     (c): The pattern is +2, +4, +2, + 4,  So, missing term = 29.

3.     (a): The pattern is (13+1),( 23+1),(33+1),( 43+1), (53+1),( 63+1)

4.     (d): The pattern is +8, +10, +12, +14, So,missing term = 70 + 18 = 88.

5.     (b): last number multiple two and also add two in each step

6.     (a): The pattern is +2, +4, +8, +16, So, missing term = 28 + 8 =36.

7.    (c): The pattern is +11, +22, +33, So, missing term = 72+ 44 = 116.

8.    (c): The pattern is +3, +6, +12, +24, So,missing term = 46 + 48 = 94.

9.    (a): The given series consists of squares of consecutive prime numbers i.e. 22, 32, 52,…… 112 132 172
      So, missing term = 72 = 49.

10.  (d): The pattern is x 3. So, missing term = 108 x 3 = 324.
