You borrow $600 from a friend the first week and pay the friend back $20 each week thereafter. Write the first six terms in the sequence.
The first six terms in the sequence can be calculated as follows:
- Week 1: $600 (borrowed)
- Week 2: $600 - $20 = $580
- Week 3: $580 - $20 = $560
- Week 4: $560 - $20 = $540
- Week 5: $540 - $20 = $520
- Week 6: $520 - $20 = $500
So, the first six terms in the sequence are:
$600, $580, $560, $540, $520, $500.
