Answer:
The age of the father is 50. The age of the son is 25.

The difference is always the son's age, and only one number works for 25, and that's 50.
x = 25
The situation described above forms an arithmetic series with first term (a1) equal to 22 and common difference (d) equal to 3. The sum of the first 10 terms is calculated by,
Sn = (n/2) x (2a1 + (n - 1) x d))
Substituting,
S10 = (10/2) x (2 x 22 + (10 - 1) x 3))
The value is 355. Therefore, the answer is letter "B. $355"
