Answer 2

The missing numbers are 51 and 103.

Step-by-step explanation:

The given sequence are:

25, 38, ?, 64, 77, 90, ?

The pattern follow:

Previous number + 13.

38 = 25 + 13 = 38

? = 38 + 13 = 51

64 = 51 + 13 = 64

77 = 64 + 13 = 77

90 = 77 + 13 = 90

? = 90 + 13 = 103

Hence, the missing numbers are 51 and 103.
