Question

Select the number that can replace the question mark (?) in the following series.
848, 969, ?, 1282, 1478

A.

999

B.

1113

C.

1000

D.

1013

Correct option is B

Given: 848, 969, ?, 1282, 1478
Logic: Difference of two consecutive terms is square of natural numbers starting from 112,122,132,142
Check the differences between consecutive terms:
969 - 848 = 121, ? - 969, 1282 - ?, 1478 -1282 = 196
Observing the differences:
121 → ? → ? → 196
121 = 112
196 = 142
If the pattern follows 112,122,132,142
122 =144
132 =169
The next term will be: 
? = 969 + 144 = 1113
Thus, the correct answer is (B) 1113.
