Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:-

$\small\sf{a=10}$

$\small\sf{d=7-10=-3}$

$\small\sf{l=-62}$

$\small\sf{where,}$

$\small\sf{l=a+(n-1)d}$

$\small\sf{-62=10+(n-1)(-3)}$

$\small\sf{-72=(n-1)(-3)}$

$\small\sf{n-1=24}$

$\small\sf{n=25}$

So, there are 25 terms in AP

The 11th term from the last term will be 18th term.

$\small\sf{a15=10+(15-1)(-3)}$

$\small\sf{10-42}$

$\small\sf{-32}$

i.e., the 11th term from the last term is -32.
