Answer 1

$\huge\color{yellow}{\underline{\underline{answer\::}}}$

0.5

Given :-

• a1 = 0.5

• a2 = 1

• a3 = 1.5

To Find :-

• d or say common difference

Formula used :-

• d1 = a2 - a1

• d2 = a3 - a2

Solution :-

• d1 = 1 - 0.5
• d1 = 0.5

• d2 = 1.5 - 1
• d2 = 0.5

Hence , d1 = d2 = 0.5

So, ⁂ d = 0.5

Hope it helps....

Answer 2

QuesTion

Find d, when 0.5, 1, 1.5, A are in A.P.

Correct AnsWer

Given

• A1 = 0.5
• A2 = 1
• A3 = 1.5

We Find

"Common difference" or "D"

We Know

Problem Solving by Below Formulas :-

• $\sf \boxed {\red{ D1 = A2 - A1 }}$

• $\sf \boxed {\red{ D2 = A3 - A2 }}$

According To The Question

D1 = A2 - A1......( 1 )

D1 = 1 - 0.5

D1 = 0.5

D2 = A3 - A2......( 2 )

D2 = 1.5 - 1

D2 = 0.5

Hence, D1 and D2 is 0.5
