Question

if 2K, 10, K + 1 are in AP find the value of k and the first term

Answer 1

★Ello ★

here is your answer !!!



a = 2k

b = 10

c = k +1

we know that


2b = a+ c


2 × 10 = 2k + k + 1

20 = 3k + 1

19 = 3k

k = 19 / 3


first term = 2k

2 × 19 / 3

=> 38 / 3


hope it help you !!


thanks !!!
