Question

The first three term of a sequence are 8y and 18 find the positive value of y so that sequence is an AP

Answer 1

Answer:

Thr value of y is 13

Step-by-step explanation:

The three terms of the sequence is given as

8, y, 18

Given that, y is a positive integer

In an A.P, a, b, c

2b = a + c

( Let a = 8, b = y, c = 18)

2y = 8 + 18

2y = 26

y = 13

The sequence 8, 13, 18 are in Arithmetic Progression i.e AP
