Correct Answer: VENTUR
Explanation:
one of the letter from beginning and one of the letter from the end of a term are removed, one by one, alternate steps
Correct Answer: 295.875
Explanation:
3
3 x 1.5 + 1.5 = 6
6 x 2.5 + 2.5 = 17.5
17.5 x 3.5 + 3.5 = 64.75
64.75 x 4.5 + 4.5 = 295.875
Correct Answer: 11250
Explanation:
The given number series is 18, 90, 450, 2250, ?
18
18 x 5 = 90
90 x 5 = 450
450 x 5 = 2250
2250 x 5 = 11250
Hence, the next number in the given series is 11250.
Correct Answer: 397
Explanation:
The pattern of given series is :
5
14 = (5x3) - 1
45 = (14x3) + 3
130 = (45x3) - 5
(?) = (130x3) + 7
=> (?) = 397
1182 = (397x3) - 9
Thus, the missing number is 397.
Correct Answer: 15
Explanation:
The terms of the given series is 1*1, 2*2 + 1, 3*3, 4*4 +1, 5*5, 6*6 + 1, . . . . .
So, 15 is wrong and must be replaced by (4*4 + 1) = 17
Correct Answer: 6630
Explanation:
Let first no. be "k" and multiple be "l"...start value of y with 3
then,
[(k x y) + {l x (l-1)}]
Thus, we get
15 x 3 + 3 x 2 = 51
51 x 4 + 4 x 3 = 216
216 x 5 + 5 x 4 = 1100
1100 x 6 + 6 x 5 = 6630
6630 x 7 + 7 x 6 = 46452
Therefore, the missing number is 6630.
Correct Answer: 32
Explanation:
The correct pattern is *1+1, *2+2, *3+3, *4+4, . . . . .
So,32 is wrong term and must be replaced by (10 * 3 + 3) = 33
Correct Answer: 15650
Explanation:
Similarly ,
Correct Answer: 22
Explanation:
In the given series,
2nd term =
3rd term =
and so on...
Here 6th term =
Therefore, 22 is wrong.
Correct Answer: 32
Explanation:
In the given series,
2nd term = 1st term + = 4 +1 = 5
3rd term = 2nd term + =5+4= 9
4th term = 3rd term + =9+9=18
5th term = 4th term + = 18+16=34
Therefore, odd term is 32
