Question

a= -7, d= 3, n=8 find an value

Answer 1

Answer:

14

Step-by-step explanation:

We know that,

$\tt{a_n = a + (n - 1) d}$

Putting the given values,

$\tt{a_n = -7 + (8 -1) × 3}$

= -7 + 21

= 14

$\tt{a_n = 14}$

Answer 2

a = - 7

d = 3

n = 8

__________ [GIVEN]

• We have to find an.

_______________________________

We know that

$a_{n}$ = a + (n - 1)d

Put the known values in above equation.

=> $a_{n}$ = (-7) + (8 - 1)(3)

=> $a_{n}$ = - 7 + (7)(3)

=> $a_{n}$ = - 7 + 21

=> $a_{n}$ = 14
