Question

if 4,5a,10 are three consecutive terms of an AP,then find the value of a​

Answer 1

Answer:

a = 1.4

Step-by-step explanation:

the series to be in AP

common difference d should be equal

d = a2 - a1 = a3 - a2

5a - 4 = 10 - 5a

5a + 5a = 10 + 4

10a = 14

a = 14/10

a = 1.4

5a = 5(1.4)

5a = 7

the series is

4, 5a, 10

4, 5(1.4), 10

4, 7, 10

hope you get your answer
