2) Find the odd number in the series: 2, 7, 28, 146, 877, 6140
Explanation:
As per the details in the question the series is in the form of
First term = 2
Second term = ( First term × 3 ) + 1
⇒ Second term = ( 2 × 3 ) + 1 = 7
Third term = ( Second term × 4 ) + 1
⇒ Third term = ( 7 × 4 ) + 1 = 28 is wrong , 29 should be sixth term because ( 7 × 4 ) + 1 = 29 .
So 28 is wrong. we get 29 as Third term.
Fourth term = ( Third term × 5 ) + 1
⇒ Fourth term = ( 29 × 5 ) + 1 = 146
Fifth term = ( Fourth term × 6 ) + 1
⇒ Fifth term = ( 146 × 6 ) + 1 = 877
3) Find the odd number in the series: 1, 2, 8, 21, 88, 445
Explanation:
As per the details in the question the series is in the form of
First term = 1
Second term = ( First term × Variable ) + Variable
⇒ Second term = ( 1 × 1 ) + 1 = 2
Third term = ( First term × Variable ) + Variable
⇒ Third term = ( 2 × 2 ) + 2 = 8 , So 8 is wrong. we get 6 as Third term.
Similarly , we can find the all terms also.
Fourth term = ( 6 × 3 ) + 3 = 21
Fifth term = ( 21 × 4 ) + 4 = 88
Sixth term = ( 88 × 5 ) + 5 = 445
4) Find the odd number in the series: 7, 23, 58, 127, 269, 555
Explanation:
The order of above series is given as
First term = 7
Second term = ( First term x 2 ) +9
⇒ Second term = ( 7 x 2 ) + 9 = 14 + 9 = 23
Third term = ( Second term x 2 ) +11
⇒ Third term = ( 23 x 2 ) + 11 = 46 + 11 = 58 is wrong , 57 should be Third term because ( 23 × 2 ) + 11 = 57 .
Similarly we can find all others terms also.
Fourth term = ( Third term x 2 ) +13
⇒ Fourth term = ( 57 x 2 ) +13
Fifth term = ( Fourth term x 2 ) +15
⇒ Fifth term = ( 127 × 2 ) + 15 = 269
Sixth term = ( Fifth term x 2 ) +17
⇒ Sixth term = ( 269 × 2 ) + 17 = 555
5) What will come in place of question mark? 156, 506, ?, 1806
Explanation:
From the above given series , we have
First term + 350 = Second term
⇒ 156 + 350 = 506
Second term + 550 = third term
⇒ 506 + 550 = ? ⇒ ? = 1056
From the given figure , we get the value of third term ( ? ) = 1056
Third term + 550 = Fourth term
⇒ 1056 + 750 = 1806
6) What will come in place of question mark? 2, 5, 10, 19, 36, ?
No Explanation found. Add Explanation and get +2 points.
7) What will come in place of question mark? 2, 3, 6, 7, 14, 15, ?
No Explanation found. Add Explanation and get +2 points.
8) What will come in place of question mark? BCFG, JKNO, RSVW , ?
Explanation:
According to position of alphabets in alphabet table , we have
B C F G → 2 , 3 ,6 , 7
J K N O → 10 , 11 , 14 , 15
R S V W → 18 , 19 , 22 , 23
{ ∴ Next sequence = Adding 8 in every position of previous sequence alphabets }
Next sequence = 18 + 8 , 19 + 8 , 22 + 8 , 23 + 8
Next sequence = 26, 27, 30, 31 = 26, 27 - 26 = 1, 30 - 26 = 4, 31 - 26 = 5 = Z A D E ( subtract the excess value by 26 )
We get , 26 , 1 , 4 , 5 → Z A D E = ( ? ) .
9) What is the angle between the hands of the clock at 3:40?
No Explanation found. Add Explanation and get +2 points.
10) If it is 09:20, then what is the angle between the hands of the clock?
Explanation:
At 9 o’ clock, the hour hand is at 270 degrees from the vertical. In 20 minutes,
Hour hand = 270 + 20*(0.5) = 270 + 10 = 280 (The hour hand moves at 0.5 dpm)
Minute hand = 20*(6) = 120 (The minute hand moves at 6 dpm)
Difference or angle between the hands = 280 – 120 = 160 degrees.
