A) 945
B) 1049
C) 1153
D) 1500​

Answer 1

The required "option (C) 1153 is correct".

Step-by-step explanation:

The given sequence are:

3, 4, 11, 60, 117, 630, ?

The follow the difference of number,

$+1, +1 \times 7, +7\times 1,+ (49+8), +57\times 9, +(513+10)....$

$4 = 3 + 1 = 4$

$11 = 4 + 1\times 7=4+7=11$

$60 = 11 + 7\times 7=11+49=60$

$117 = 60 + (49+8)=60+57=117$

$630 = 117 + 9\times 57=117+513=630$

Similarly,

$?= </strong>630 + (513+10)=630+523<strong>=1153$

∴ Missing number(?) = 1153.

Hence, the required "option (C) 1153 is correct".
