Find the next term in the series: $7, 14, 42, 168, 840, ?$ / श्रेणी में अगला पद ज्ञात कीजिए: $7, 14, 42, 168, 840, ?$

Correct Answer: $5040$
Each term is multiplied by an increasing integer: $\times2, \times3, \times4, \times5$, so the next multiplier is $6$: $840\times6 = 5040$. / गुणक $2, 3, 4, 5$ बढ़ रहे हैं; अगला $6$, अतः $840\times6=5040$। Option (a) is the trap of continuing with $\times5$ again ($840\times5 = 4200$).
