Answer Key: 1 Explanation: In the each row middle term is average of extreme terms 17+15/2 = 16, 52+26/2 = 39. So, missing number =37+45/2 = 41.Hence, the answer is option 1
1.F
2.G
3.H
4.K
Answer Key: 1 Explanation: Positions of alphabets (A to Z) is (1-26) we have:
In the first column, P-A=16-1=15=O.
In the second column, J-D=10-4=6=F.
So, in the third column, missing letter =O-I=15-9=6 =F
So the answer is option 1
Find the missing term in each of the following
1.445
2.446
3.472
4.435
Answer Key: 1 Explanation: We have:1×1+1=2, 2×2+2=6, 6×3+3 = 21, 21×4+4=88.
So, missing number=88×5+5=445 so answer is option 1
1.8
2.9
3.4
4.25
Answer Key: 3 Explanation: The two ends of each line contain a number and its square -5. e.g. 15^{2}-5=220, 18^{2}-5=319 So, missing number =3^{2}-5=4. So answer is option 3
1.70
2.206
3.106
4.100
Answer Key: 2 Explanation: The pattern is middle number is sum of extreme terms. So, missing number = 52+48+49+57=206 So the answer is option 2
1.216
2.343
3.215
4.342
Answer Key: 3 Explanation: Pattern is that each number are of the form N^{3} - 1.
N= 3 which gives 3^{3} - 1= 26
N= 4 which gives 4^{3} - 1= 63
N= 5 which gives 5^{3} - 1= 124
Hence answer would be N= 6 which gives 6^{3} - 1= 215
So answer is option 3
1.832
2.777
3.245
4.779
Answer Key: 4 Explanation: By going in clockwise direction we find the following pattern
2 + 1^{3}-1=2; 2+2^{3}-1=9; 9+3^{3}-1= 35
35+4^{3}-1=98 ; 98+5^{3}-1=222.
222+6^{3}-1=437 and 437+7^{3}-1=779
Hence, the answer is option 4
1.76
2.66
3.86
4.56
Answer Key: 1 Explanation: The pattern is as follows
45+20-27=38; 37+15-16=36; so 33+58-15=76 so answer is option 1
1.36
2.66
3.24
4.28
Answer Key: 1 Explanation: The pattern is: number in the circle is average of numbers outside the circles.
So missing number is(25+36+48+35)/4 =36 so answer is option 1
1.90
2.76
3.84
4.88
Answer Key: 1 Explanation: Going clockwise starting with 6 pattern is 6=2^{2}+2, 12 = 3^{2}+3,
20 =4^{2}+4, 30 =5^{2}+5, 42 =6^{2}+6
56 = 7^{2}+7, 72=8^{2}+8, so missing number is 9^{2}+9=90 , So answer is option 1
