- 1458

Step-by-step explanation:

a= first term

d = common difference

answer = -1458.

Answer 2

AnSwEr:

${\red\bigstar\large\bold{\mathrm{\underline{\green{Given:}}}}}$

❥ a = 54

❥ d = 51 - 54 = -3

❥ n = 10

${\red\bigstar\large\bold{\mathrm{\underline{\green{To\:Find:}}}}}$

❥ $\sf {10}^{th}\:term\:of\:A.P.$

${\red\bigstar\large\bold{\mathrm{\underline{\green{Solution:}}}}}$

$\large\bold{\mathtt{\underline{\red{Formula\:Used}}}}$

$\large\bold{\boxed{\sf{\pink{ a_n\:=\:a\:+\:(n\:-\:1)d}}}}$

$\star\sf {a}_{10}\:=\:54\:+\:(10\:-\:1)-3$

$\star\sf {a}_{10}\:=\:54\:+\:9(-3)$

$\star\sf {a}_{10}\:=\:54\:-\:27$

$\star\sf {a}_{10}\:=\:27$

${\red\bigstar\large\bold{\mathrm{\underline{\green{{10}^{th}\:term\:of\:A.P.\:=\:27}}}}}$
