Interest will be the smallest at the sixth instalment which is $859.2033.

Step-by-step explanation:

Amount borrowed: $120,000

Instalments: 6

Amount paid each year: 120,000/6 = $20,000

Interest: 6.5%

Formula to calculate each instalment = yearly instalment+(amount borrowed * interest)

Formula to calculate outstanding amount = Amount borrowed - previous instalment

First instalment: 20,000 + (120,000 x 6.5%) = $ 27,800

Outstanding amount = 120,000-27800 = $112,200

Second instalment: 20,000 + (112,200 x 6.5%) = $27,293

Outstanding amount = 112,200-27,293 = $84,907

Third instalment: 20,000 + (84,907 x 6.5%) = $25,518.955

Outstanding amount = 84,907-25518.955 = $59,389

Fourth instalment: 20,000 + (59,388.045 x 6.5%) = $23,860.223

Outstanding amount = 59,388.045-23,860.223 = $35527.822

Fifth instalment: 20,000 + (35,527.822 x 6.5%) = $22309.30843

Outstanding amount: 35,527.822-22309.30843 = $13218.51357

Sixth instalment: 20,000 + (13218.51357 x 6.5%) = $20,859.2033

Interest will be the smallest at the sixth instalment which is $859.2033.
