Correct Answer: $74$
Successive differences are $4, 6, 10, 18$; each difference exceeds the previous by a doubling increment ($+2, +4, +8$), so the next difference is $18+16 = 34$, giving $40+34 = 74$. / अंतर $4, 6, 10, 18$; अगला अंतर $34$, अतः पद $74$। Option (a) is the trap of adding a constant $+8$ difference pattern ($40+26$).
