​

Answer 1

Step-by-step explanation:

In the given A.P sequence 2,5,8... the first term is a=2 and the common difference is d=3.

Also, S

2n

=

2

2n

[2a+(2n−1)d] ...(1)

⇒S

2n

=

2

2n

[2(2)+(2n−1)3]

⇒S

2n

=

2

2n

[4+(2n−1)3]

Also,the first term and the common difference of the sequence 57,59,61,... are a=57 and d=2 respectively.

S

n

=

2

n

[2a+(n−1)d] ...(1)

⇒S

n

=

2

n

[2(57)+(n−1)2]

=

2

n

[114+(n−1)2] ....(2)
