Question

the sum of ap of a-2, a ,a+2 is 15 then a is​

Answer 1

Answer:

A.T.Q

a - 2 + a + a + 2 = 15

3a = 15

a = 5

Answer 2

Answer:

a=15

The difference of the two successive integers in an algebraic progression (AP) series of numbers is always the same amount. It also goes by the name Arithmetic Sequence.

Step-by-step explanation:

It is referred to as AP, a logical sequence in which there is always a constant difference between the 2 terms. A progression of numbers known as an arithmetic series is one in which, for every pair of terms in a row, the next number is derived by adding an approximate number to the first.

A sequence or series of numbers is said to be in arithmetic progression (AP) if the common difference between any two successive numbers in the sequence is always the same.

AP of this equation.

$(a-2)+(a+2)+\frac{a}{3} =15.$

by sending ÷3 to RHS.

we get $15*3=45$

so,

$a+2+a-2+a = 45.$

$3a = 45\\a = 15$
