Question

If the sum of first n terms of a series
is (n +12), then what is its third
term?​

Answer 1

Step-by-step explanation:

Sn​=n+12[Given]

Therefore,

S2​=2+12=14

S3​=3+12=15

⇒T3​=S3​−S2​=15−14=1

 hope it helps

Answer 2

Answer is 1

Sn = (n+12)

s2 = ( 2+12)=14

s3 = (3+12)= 15

So, term 3 = S3 - S2= 15-14 =1
