Step-by-step explanation:

There are two formulae to find the sum of the terms of an AP.

In this case we know the following:

a

=

2

d

=

4

n

=

10

S

n

=

n

2

[

2

a

+

(

n

1

)

d

]

S

10

=

10

2

[

2

(

2

)

+

(

9

)

4

]

S

10

=

5

[

4

+

36

]

S

10

=

200

The other formula requires the last term, which is this case we do not know, but if necessary, we could work out.

S

10

=

n

2

(

a

+

l

)
