Answer 2

Answer:

13

Explanation:

The mentioned sequence follows the rule as - Adding the first two numbers and then subtracting the third one from it.

Thus,

a. 354:4

= 3+5-4

= 8-4 = 4

b. 852:11

= 8+5-2

= 13-2 = 11

c. 794:12

= 7+9-4

= 16-4 = 12

d. 951:?

= 9+5-1= 13

Therefore 951 : 13. The complete sequence = 354 : 4 :: 852 : 11 :: 794 : 12 :: 951 : 13
