Question

The sum of three consecutive terms of an ap is 72 ..then the middle term is?

Answer 1

Answer:

Middle term is 24

Step-by-step explanation:

let us assume the 3 consecutive a.p terms be  a-d , a , a+d

we are given with the sum of the a.p as 72. so,

a-d + a + a-d = 72

3a = 72

a = 24 (which is the middle term of the assumed a.p)

Answer 2

Answer:

let, us suppose three consecutive terms are (a - d ) (a) (a + d)

☑ There sum is 72

↪ ( a - d) + (a) + ( a + d) = 72

↪a - d + a + a + d = 72

↪ 3a = 72

↪ a = 72 /3

↪ a = 24

So, In the three consecutive terms of a Ap ( a - d) (a) (a + d)

(a ) is middle term

Therefor The middle term is

a = 24
