Question

If 20, k, 32 are in AP find ke solve it

Answer 1

Answer:

26

Step-by-step explanation:

Given:

• The numbers 20,k and 32 are given to be in Arithmetic progression

To find:

• The value of k in the arithmetic progression

In an arithmetic progression the common difference between each and every term is equal

So,

k-20=32-k

K+k-20=32

2k-20=32

2k=32+20

2k=52

k=52/2

k=26

The value of k in the arithmetic progression is equal to 26

Extra:

• In AP the first term is denoted by a
• The number of terms is denoted by n
• The common difference is denoted by the term d
• Nth term of an AP is denoted by : a+(n-1)d
• Sum of n terms of an AP = n/2(2a+(n-1)d)
