The first missing number in the sequence is 35, and the last missing number is 77.
<h3>Next number of the given sequence</h3>
The two missing numbers in the given sequence is calculated as follows;
= ?    49     63    ?
The given sequence is factor 7 which increases by 2
= 7 x 5      7 x 7       7 x 9     7 x 11
= 35         49          63          77
Thus, the first missing number in the sequence is 35, and the last missing number is 77.

The height of glass 1 is 7.6
so, you find the volume of glass 2,= 26.376
then you subtract the answer from 80 cubic cm to get the volume of glass 1
                           80 - 26.376 = 53.694
then you work backwards to get the height, which is 7.6

For this case we have the following expression:
 (x + 7) / (x ^ 2 - x - 2) = A / (x - 2) + B / (x + 1)
 Rewriting we have:
 (x + 7) / ((x-2) (x + 1)) = A / (x - 2) + B / (x + 1)
 We multiply the equality by (x-2) (x + 1):
 x + 7 = A (x + 1) + B (x - 2)
 Rewriting we have the following system of equations:
 A + B = 1
 A - 2B = 7
 Solving the system we have:
 A = 3
 B = -2
 Answer:
 constants A and B are:
 A = 3
 B = -2
