Find the 8th term of the sequence below.
Tn = 2n²-3n - 6
T8 =
Sorry again I don’t understand how to do this :(

Answer 1

8th term = 98

Explanation:

Given equation,

→ Tn = 2n² - 3n - 6

Now the 8th term will be,

→ Tn = 2n² - 3n - 6

→ T8 = 2(8)² - 3(8) - 6

→ T8 = 2(64) - 24 - 6

→ T8 = 128 - 30

→ [ T8 = 98 ]

Hence, the 8th term is 98.
