Question

if the nth term of any progression is 4n^-l then the 8th term is
​

Answer 1

Given:

• The nth term of the AP is 4n² - 1

Find:

• 8th 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

➣ aₙ = 4n² - 1

➣ a₈ = 4(8)² - 1

➣ a₈ = 4 ༝ 64 - 1

➣ a₈ = 256 - 1

➣ a₈ = 255

• The 8th term of the AP is 255.
