Question

what is common difference of AP 1 .. a-b , a ,a +b is
a) a
b)b
c) a- b
d) a +b​

Answer 1

Step-by-step explanation:

$\underline\red{⛄~SOLUTION~⛄}$

$\underline\red{Common~difference~(d)}$ = a - (a - b)

$\huge\bold\green{~❀~}$ → a - a + b

Cancel +a and -a

• $\huge\bold\green{~❀~}$ b

Therefore , the common difference of above given AP is $\rm\red{b}$ .

• $\sf\blue{Option~b)~b}$ ✔
