Question 17:
This is an arithmetic progression problem.

  1. Identify the given terms in the arithmetic progression (AP).

    We are given the 4th4^{th} deposit (a4a_4) and the 6th6^{th} deposit (a6a_6).
    a4=150 000a_4 = 150\,000 FCFA
    a6=250 000a_6 = 250\,000 FCFA

  2. Use the formula for the nthn^{th} term of an AP, an=a1+(n−1)da_n = a_1 + (n-1)d, where dd is the common difference.
