Answer 2

Hey there this is the answer. Please mark my answer the brainliest.

36 = 6 / 2( 2a + 6 - 1d )

36 =3 ( 2a+5d )

2a + 5d = 12 ....(i)

Again s16 = 16 / 2 [ 2a + 15d ]

256 = 8( 2a + 15d )

2a + 15d = 32......(ii)

From 1&2 10d = 20, d=2

Or a=1

Now s10 = 10/2 ( 2 × 1 + 10 - 1 × d )

= 5 ( 2 + 9 × 2 )

= 5 × 20

= 100.
