Question

Find 11th term, 12th term, 20th term sum of 12,20,33 term​

Answer 1

Answer:

t

n

=

a

+

(

n

−

1

)

d

where:

t

n

=

any term in the arithmetic sequence

a

=

first term

n

=

term number/number of terms

d

=

common difference

To find the

12

t

h

term of the sequence, we first need to find

d

, the common difference. We can do this by subtracting

t

1

from

t

2

:

t

2

−

t

1

=

14

−

20

=

−

6

Now that you have the common difference, substitute all your known values into the formula to solve for

t

12

:

t

n

=

a

+

(

n

−

1

)

d

t

12

=

20

+

(

12

−

1

)

(

−

6

)

t

12

=

20

+

(

11

)

(

−
