if the digit is >5, it +1 to the tenth digit. If it's <5, it will be reduced to 0.

To determine the sum of the sequence, we can finfd the first five terms however it would be tedious. Instead, we can find the sum by the expression:
S(n) = a(1) ( 1 - r^n) / 1-r
S(5) = -2 (1 - (-3)^5) / 1-5
<span>S(9) = 122 <------------OPTION B</span></span>
