Question

1) In an A.P if S10 = 35 and S9 = 28 find a10

Answer 1

We know that

$\fbox\blue{An = Sn - Sn-1}$

So,

$\pink{A10 = S10 - S9}$

$\pink{A10 = 35 - 28}$

$\pink{A10 = 7}$

Answer 2

Answer:

THE ANSWER WILL BE

A10 = 7.

Step-by-step explanation:

GIVEN,

An=Sn-Sn-1

SO, A10= S10-S9

A10=35

therefore, A10= 7
