Question

How many terms are there in the ap:-1 ,-5/6 ,-2/3,....10/3?

Answer 1

Answer:

Total terms = 27

Step-by-step explanation:

-1, -5/6, -2/3,....10/3

a = -1

d = -5/6-(-1)

d = -5/6+1

d = 1/6

an = a + (n-1)d

10/3 = -1 + (n-1) ×1/6

10/3 + 1 = (n-1) ×1/6

13/3 = (n-1) ×1/6

13/3×6 = n-1

26 = n - 1

27 = n
