Answer : Option A
Explanation :
We have :
I: 5 27 61 122 213 340 509
II: 22 34 61 91 127 169
III: 12 27 30 36 42
IV: 15 3 6 ; 6
Clearly, the given series becomes a triangular pattern series if each term in IV: is 6.
Again, in II: 34 must be replaced by (61 - 24) i.e., 37 and 22 by (37 - 18) i.e., 19.
Thus, in the given series, 27 is wrong and must be replaced by (5 + 19) i.e., 24.
