Correct options :
22. 3
25. 2
Step-by-step explanation:
Question 22 :
Given terms : 0 , 2 , 4 _ , 20, 30.
A general formula for the common difference between the terms { derived, based on this question } for nth term : 2n , where n( € W ) refers the number of terms .
Checking the derived formula :
- Difference between 1st and 2nd terms : 2( n ) = 2( 1 ) = 2 [ i.e. 2 - 0 ]
- Difference between 2nd & 3rd term : 2( 2 ) = 4 [ i.e. 6 - 2 ]
Similarly :
Difference between 3rd & 4th term = 2( 3 ) = 6
Here,
3rd term= 6
= > 4th term - 3rd term = 6
= > 4th term - 6 = 6
= > 4th term = 12
Using the same formula :
Difference between 6th & 7th term = 2( 6 ) = 12
Given,
6th term = 30
= > 7th term - 6th term = 30
= > 7th term - 12 = 30
= > 7th term = 42
Question 25 :
HUNDRED is written as NUHDDER.
On the basis of the certain observations, it can be said :
The digits after & before the centre{ except the digit at centre } are getting reversed.
Digits before the digit at centre : HUN , is written as NUH which is the reversed order of HUN.
Similarly with the last three digits : RED, written as DER, which is the reversed order of RED.
Using the same pattern :
KITCHEN can be written as : Reverse order of KIT ; C ; reverse order of HEN i.e. TIKCNEH.
