Question

22. Find the 12 th term from the
end of an AP -2,-4,-6,...-100. *
​

Answer 1

Answer:

the answer is -78

Step-by-step explanation:

first you have to reverse the series like this,

-100,.......-6,-4,-2.

then,

a = -100

d = 2

n = 12

then,

T12 = a+11d

= -100+11(2)

= -100+22

= -78.

hence answer will be -78
