Answer 2

Answer:

0

Step-by-step explanation:

Sum of n terms of A.P.

Sn= an + bn

then sum of first term ,

S1 = a(1) + b(1) = a + b

sum of first two terms,

S2 = 2a + 2b

1st term

a1 = a + b

2nd term

a2 = S2 - S1

a2 = 2a + 2b - (a + b)

a2 = a + b

Now, difference = 2nd term - 1st tedm

d = a2 - a1

d = a + b - (a + b) = 0

Difference is equals to zero.
