Answer 1

Answer:

this is answer for your question

Answer 2

$\huge\underline\mathrm\red{GivEn:-}$

$a \: = - 3$

$d = \frac{ - 1}{2} - ( - 3) = \frac{ - 1 + 6}{2}$

$d = \frac{5}{2}$

$n = 111$

$\huge\underline\mathrm\red{To\: Find:-}$

$find \: 111th \: term .$

$\huge\underline\mathrm\red{SoLutioN:-}$

To find 111th term of A.P., we use the formula

$\large{\boxed{\bf{\green{an = a + (n-1)d}}}}$

According to question :-

$\implies$ an = -3 +(111-1)$\large{\sf {\frac{5}{2}}}$

$\implies$ an = -3 + 110 x $\large{\sf {\frac{5}{2}}}$

$\implies$ an = -3 + 55 x 5

$\implies$ an = -3 + 275

$\large{\boxed{\bf{\green{an = 272}}}}$
