Answer:

2) 19247 ........................

Answer 2

The value of "missing number (?) option 4) 117642" is correct.

Step-by-step explanation:

The given series:

6, 60, 620, 7770, ?

To find, the value of missing number (?) = ?

The pattern follow:

$3^{2} -3,4^{3} -4,5^{4} -5,6^{5} -6,7^{6} -7,........$

6 = $3^{2}$ - 3 = 9 - 3 = 6

60 = $4^{3}$ - 4 = 64 - 4 = 60

620 = $5^{4}$ - 5 = 625 - 5 = 620

7770 = $6^{5}$ - 6 = 7776 - 6 = 7770

Similarly,

? =  = $7^{6}$ - 7 = ($7^{3}$)($7^{3}$) - 7 = (343)(343) - 7 = 117649 - 7 = 117642

∴ Missing number (?) = 117642

Thus, the value of "missing number (?) option 4) 117642" is correct.
