Directions: What should come in place of question mark (?) in the following number series?
The given series is in the pattern
+ 4, + 8, + 12, + 16, ..........
So , the missing term
= 41 + 20 = 61
×1, ×2, ×3, ×4, ..........
= 24 × 5= 120
×2 + 1, × 2 + 2, × 2 + 3,.......
= 59 × 2 + 4
= 122
(22 – 1), (42 – 1),.......... (82 – 1), (102 – 1), (122 – 1).
So, the missing term is (62 – 1)
= 36 - 1
= 35
÷ 6, ÷ 5, ÷ 4, ÷ 3, ÷ 2.
So, the missing term is
960 ÷ 5
= 192
Series is
\[9^2,8^3,7^4,6^5,5^6,4^7,3^8\]
\[?=3^8\]
\[=6561\]
23 , 43 , 63 , 83 , 103 , 123 , .....
Then,
? = 143
= 2744
The series is
2187 ÷ 3, 729 ÷ 3, 243 ÷ 3, 81 ÷ 3, 27 ÷ 3, 9 ÷ 3, (3 ÷ 3 = 1)
