)
(1st *2nd )- total number -3rd term = 4th number
11 x 9 - 5 = 99 - 5 = 94
5 x 6 - 14 = 30 - 14 = 16
Similarly, 9 x 7 - 13 = 63 - 13 = 50
Hence, "50" is the correct answer.
(1st term)+(2nd term)+(3rd term)โ(total number)-3= 4th number
11 + 9 + 7 โ 27 - 3 = 24
17 + 6 + 4 โ 27 - 3 = 24
Similarly, 12 + 12 + 9 โ 33 - 3 = 30
Hence, "30" is the correct answer.
(1st + 2nd + 3rd) = Total/2 =4th number
6 + 9 + 11 = 26, 26/2 = 13
12 + 4 + 6 = 22, 22/2 = 11
Similarly, 7 + 11 + 2 = 20, 20/2 = 10
Hence, "10" is the correct answer.
(1st term * 2nd term) = (Total term - 3rd term) = 4th term
5 x 9 = 45 - 6 = 39
3 x 11 = 33 - 7 = 26
8 x 5 = 40 - 4 = 36
Hence, "36" is the correct answer.
7 + 12 + 3 = 22
3 + 15 + 2 = 20,
5 + 6 + 9 = 20
Hence, "20" is the correct answer.
(1st term * 2nd term + 3rd term) = 4th term
6 ร 5 + 4 = 30 + 4 = 34
3 ร 5 = 15 + 8 = 23
7x + 9 = 30 โ 7x = 21 โ x=3.
Hence, "3" is the correct answer.
(2nd term -1) = (Total * 1st term) = 3rd term
13-1=12, 6 ร 12 = 72
7-1=6, 4 ร 6 = 24
11-1=10, 9 ร 10 = 90
Hence, "90" is the correct answer.
(1st term + 2nd term) = (Total term * 3 - 1st term) = 3rd term
6 + 13 = 19; 19 ร 3 - 6 = 51
4 + 7 = 11; 11 ร 3 - 4 = 29
19 + 11 = 30; 30 ร 3 - 19 = 71
Hence, "71" is the correct answer.
In row 1st 39 + 28 = 67.
3rd row; 28+47=75.
2nd row ? + 14 =51 โ? =37
Hence, "37" is the correct answer.
Logic (in row): - (3rd No. + 1st No./2) = 2nd No.
49 + 24/2 = 49 + 12 = 61
66+56/2 =66 + 28 = 94
61 + 32/2 = 61 + 16 = 77
Hence, "77" is the correct answer.
