120

Correct Answer:

Explanation:

The pattern of number series is follows:
9050 - 15³ = 9050 - 3375 = 5675
5675 - 13³ = 5675 - 2197 = 3478
3478 - 11³ = 3478 - 1331 = 2147
2147 - 9³ = 2147 - 729 = 1418
1418 - 7³ = 1418 - 343 = 1075 ?1077

Correct Answer:

Explanation:

Correct Answer: 120

Explanation:

The given series is -
(9 x 9), - (9 x 8), - (9 x 7), - (9 x 6), - (9 x 5)

Correct Answer: 734

The given series is
+ (14)², + (13)², + (12)², + (11)², + (10)²

Correct Answer:

Explanation:

The series is + 7, + 11, + 13, + 17, + 19, + 23
11 + 7 = 18, 18 + 11 = 29, 29 + 13 = 42, 42 + 17 = 59, 59 + 19 = 78, 78 + 23 = 101
The wrong number is 34650; 17325 x 3 = 51975

Correct Answer: 32

Explanation:

The series is ( + 7 x 1), (+ 6 x 2), (+ 5 x 3), (+ 4 x 4), (+ 3 x 5), (+ 2 x 6).
The wrong number is 32;
(9 + 6) x 2 = 15 x 2 = 30
