Sagot :
x=1 after the first 5 years;
x=2 after the another 5 years (or better said after the first 10 years in the bank);
x=3 after another 5 years ( or better said after the first 15 years in the bank)
and so on...
x is the number of 5 years intervals which have passed up to a moment in time :)
x=2 after the another 5 years (or better said after the first 10 years in the bank);
