Answer 2

Answer:

Let first term be a and common difference d.

Using formula :

S_n = n / 2 ( 2 a + ( n -1 ) d )

150 = 10 / 2 ( 2 a + 9 d )

30 = 2 a + 9 d

2 a = 30 - 9 d ... ( i )

126 = 9 / 2 ( 2 a + 8 d )

14 × 2 = 2 a + 8 d

2 a = 28 - 8 d ... ( ii )

From ( i ) and ( ii )

30 - 9 d = 28 - 8 d

2 = d

2 a = 28 - 8 d ... ( ii )

2 a = 28 - 16

a = 6

Now :

Using formula :

t_n = a +  ( n - 1 ) d

a = 6

d = 2

n = 10

t_10 = 6 + 9 × 2

t_10 = 6 + 18

t_10 = 24.

Final answer is 24.
