Answer 2

Answer:

$\star\large\mathcal{\underline{\underline{PLEASE \: }}}\large\mathcal\red{\underline{\underline{F}}}\large\mathcal\green{\underline{\underline{OLL}}}\large\mathcal\pink{\underline{\underline{OW \: }}}\large\mathcal\blue{\underline{\underline{ME}}}\star$

Step-by-step explanation:

$9, 4, -1, -6, -11, .....$

$here , first \: term, \: a1 = 9$

$and , \: common \: difference, \: d = 4-9 = -5$

$Also, n = 27$

$a27 = a1 + (n-1)×d$

$=> 9 + (27-1)(-5)$

$=> 9+ (26)×(-5)$

$=> 9 -130$

$=> -121$

$therefore , the \: 27th \: term \: \\ \: of \: the \: A.P \: is -121.$
