Question

20th term of the AP -5,-3 ,-1,1 is ​

Answer 1

Answer:

Answer is 33.

Step-by-step explanation:

In the given A.P

firts term(a)= -5

common difference(d)= -3-(-5)

= 2

n=20

20th term of the A.P= a+(n-1)*d

= -5+(20-1)*2

= -5+38

=33.

Therefore 20th term of the given A.P is 33.

Answer 2

Answer:

$a = - 5$

$a2 = - 3$

$d = a2 - a1$

$d = 3 - ( - 5) = - 3 + 5 = 2$

Here an=20

we use this formula =a+(n-1)d

$an = a + (n - 1)d$

$an - 5 + (20 - 1)2$

$an = - 5 + 38$

$an = 33$

$20th \: term \: of \: the \: ap - 5 - 3 - 11 \: is \: 33$
