Question

if Sn denotes the sum of n terms of an A P then S12-S11 is the ______ term of the AP

Answer 1

$S_{12}-S_{11}$ is the twelfth term of the AP

Step-by-step explanation:

We are given a arithmetic progression.

$S_n$ denotes the sum of n terms of the A.P

Thus,

$S_{12}$ is the sum of 12 terms of AP

$S_{11}$ is the sum of first 11 terms of AP

Then,

$S_{12}-S_{11}$

= Sum of first 12 terms - Sum of first 11 terms

$= 12^{th}\text{ term}$

$S_{12}-S_{11}$ is the twelfth term of the AP
