Question

in an arithmetic progression if a= 28 d=-4 N=7 then find the nth term​

Answer 1

$\huge\underbrace\mathcal\pink{anSwer}$

Given:

a = 28,

d = -4

n = 7

nth term of the AP = a + (n-1) d

⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀= 28 + (7-1)(-4)

⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀= 28 -24

⠀⠀⠀⠀⠀⠀ ⠀⠀⠀⠀⠀⠀= 4 ans.

Answer 2

Step-by-step explanation:

A n = A 7

A 7 = a + ( n - 1 ) d

= 28 + (7-1) -4

= 28 + 6 × -4

= 28 - 24

= 4
