10,7,4.........ಈ ಸಮಾಂತರ ಶ್ರೇಢಿಯ 10ನೇ ಪದ ಕಂಡುಹಿಡಿಯಿರಿ?​

Answer 1

$Given \: A.P : 10, 7, 4, \ldots$

$First \:term \: ( a = a_{1}) = 10$

$Common \: difference (d) = a_{2} - a_{1}$

$= 7 - 10$

$= -3$

$\boxed{\pink{ n^{th} \: term (a_{n}) = a+(n-1)d }}$

$Here , n = 10$

$10^{th} \: term = a_{10}$

$= a + (10-1)d$

$= 10 + 9 \times (-3)$

$= 10 - 27$

$= -17$

Therefore.,

$\red{ n^{th} \: term (a_{n})} \green { = -17 }$
