Question

Find the middle term of the AP 10, 7, 4, ..., (-62).​

Answer 1

Answer:

-26

Step-by-step explanation:

A=10

D=-3

Last term of AP = -62

An = A + (n-1)d

-62 = 10 + (n-1) (-3)

-72/-3 = n-1

24 = n-1

n = 25

Therefore, Middle term = 25+1/2 th term

=26/2

= 13

Therefore ,

A13 = A+ 12d

A13 = 10 +12(-3)

A13 = 10-36

A13 = -26

Therefore middle term is -26
