i) 10,4,-2​

Answer 1

Step-by-step explanation:

7 4 - 62 .

Sol: an=a + (n-1)d

-62=10+(n-1)(-3)

-62=10-3n+3

3n=75

n=25

Answer 2

→ a = 10

→ d = 4 - 10 = -6

To find :- 11th and 14th term of an AP

Solution:-

→ a11 = a + 10d

→ a11 = 10 + 10(-6)

→ a11 = 10 - 60

→ a11 = - 50

11th term of an AP is - 50

→ a14 = a +13d

→ a14 = 10 + 13 (-6)

→ a14 = 10 - 72

→ a14 = - 62

14th term of an AP is -62
