Question

If the 1st and 11th term of an A.P are 3 and 43 respectively, find the common difference.

Answer 1

Step-by-step explanation:

first term = a = 3

11th term = a + 10d = 43

subtract first term from 11th term

a + 10d = 43

- a. = - 3

10d = 40

d = 40/10 = 4

therefore the common difference d = 4
