Answer 2

Answer:

(D) 4

Step-by-step explanation:

Given sequence is 7, 9, 8, 6, 10, 9, 5, 11, 10, ?, 12

let unknown = x

There are three series present in given sequence.

$1^{st}$ series is 7, 6, 5, x

$2^{nd}$ series is 9, 10, 11, 12

$3^{rd}$ series is 8, 9, 10

In first series we are taking difference of 1 in pervious number to find next number.

∴ x = subtracting 1 in 5 = 5 - 1 = 4  

∴ Missing number is 4.

So option (D) is correct.
