Answer 1

Answer:

255

Step-by-step explanation:

Put the value 8 in the place of n

Answer 2

Answer:

The $8^{th}$ term of the AP is 255.

Given:

The $n^{th}$ term of an AP is$4n^2-1$

To find:

$8^{th}$ term of an AP

Solution:

The arithmetic progression sequence can be represented as  a, a + d, a + 2d,

Where a = first term, difference between two terms = d

$a_{n}=4 n^{2}-1$

$a_{8}=4(8)^{2}-1$

$a_{8} =4 \times 64 – 1$

= 256 – 1

$a_{8} = 255$

Result:

The $8^{th}$ term of the AP is 255.
