Question

Find the 11th term of the A.p -5,-5/2,0,5/2

Answer 1

Answer:

Step-by-step explanation:

A= -5 d=5/2. N=11.

An=a+(n-1)d

= -5 +( 10 -1 ) 5/2

=. -5 +(25-5/2)

= -5 +(45/2)

= -5 +45/2

=. -10/2 +45/2

A16 =. 35/2

Answer 2

• a = -5
• d = -5/2 + 5
• = (-5 + 10)/2
• = 5/2
• d = 5/2
• a(11) = a + 10d
• = -5 + 10×5/2
• = -5 + 25
• = 20
• a(11) = 20
