Question

Find the 8th Term of the AP _4_2,0...

Answer 1

Answer- t8= 10

Explaination- t1=a= -4

d=t2-t1=-2-(-2)

2

t8=a+(n-1)d

=-4+ (8-1)2

=-4+7×2

=-4+14

=10

Answer 2

Answer:-

8th term of AP is 10

$\rule{300}{2}$

Full Solution:

Given:-

AP→ -4,-2,0...

First term, A=-4

Common difference, d=A2-A1

Common difference, d=-2-(-4)

Common difference, d=-2+4

Common difference, d=2

$\rule{300}{2}$

To find:-

8th term of AP

$\rule{300}{2}$

Step-by-step explanation:-

We have formula for nth term of AP:

AN=A+(N-1)d

We have to find 8th term of AP so N will be 8.

Put given parameters in the formula:

→ A8=-4+(8-1)2

→ A8=-4+7(2)

→ A8=-4+14

→ A8=10

∵8th term of AP is 10.
