The given series is in pattern + 4, + 8, + 12, + 16, ...............
So, the missing term = 41 + 20 = 61

The given series is the pattern x1, x2, x3, x4, .............
so, the missing term = 24 x 5 = 120

the given series is in the pattern x 2 + 1, x 2 + 2, x 2 + 3,............
So, the missing term = 59 x 2 +4 = 122

The given series is in the pattern (2² - 1), (4² - 1),............ (8² - 1), (10² - 1), (12² - 1). So, the missing term is (6² - 1) = 35

The given series is in pattern ÷ 6, ÷ 5, ÷ 4, ÷ 3, ÷ 2. So the missing term is 960 ÷ 5 = 192

The difference between the numbers increases by 1.

The gap is of -9

Series is 2³ , 4³ , 6³ , 8³ , 10³ , 12³ , ....
Then, ? = 14³ = 2744

Option (e) Series is 9² , 8³ , 7⁴ , 6⁵ , 5⁶ , 4⁷ , 3⁸
? = 3⁸ , = 6561

6 x 5 -4 = 26
26 x 5 + 4 =134
134 x 5 - 4 =666
666 x 5 + 4 = 3334
3334 x 5 -4 = 16666
16666 x 5 + 4 = ?
? = 83334
