Answer 2

Question :- 2, 5, 8, ……………., 35 is the fourth term at the end of the arithmetic series ?

1) 29

2) 26

3) 23

4) 20

Solution :-

we know that in an AP,

• first term = a = 2
• common difference = d = 5 - 2 = 3
• Tn = a + (n - 1)d = 35

so,

→ a + (n - 1)d = 35

→ 2 + (n - 1)3 = 35

→ 2 + 3n - 3 = 35

→ 3n - 1 = 35

→ 3n = 35 + 1

→ 3n = 36

→ n = 12 .

therefore,

→ 4th term from last = 12 - 4 = 8th term .

hence,

→ T(8) = a + (8 - 1)d

→ T(8) = 2 + 7 * 3

→ T(8) = 2 + 21

→ T(8) = 23 (Ans.)
