4 | 9 | 25 | 103 | ||
3 | (a) | (b) | (c) | (d) | (e) |
Which of the following numbers will come in place of (c)? |
The given series is in the below pattern ,
First series :-
First term = 4
Second term = First term × 2 + 1
? Second term = 4 × 2 + 1 = 9
Third term = Second term × 3 - 2
? Third term = 9 × 3 - 2 = 25
similarly , we can find the all others terms .
......... and so on .
Second series :-
First term = 3
Second term = First term × 2 + 1
? Second term = 3 × 2 + 1 = 7
Third term = Second term × 3 - 2
? Third term = 7 × 3 - 2 = 19
Fourth term = Third term × 4 + 3
? Fourth term = 19 × 4 + 3 = 79
Hence , the place value of ( c ) is 79 .
