CAN SOME ONE PLEASE TELL ME THE ANS​

Answer 1

$\huge \sf \mathfrak \blue{ \underline {Answer }}$

$\sf \rightarrow3,6,9,12$

$\sf \rightarrow here \: t_{1} = 3 , \sf t_{2} = 6 , \sf \: t_{3} = 9 \: and \: \sf t_{4} = 12$

$\sf \:as \: we \: know \: that, t_{1} = \pink {a} \:$

$\sf difference \: between \: 2 \: consecative \: numbers \: is \: \pink{d}.$

$\sf \therefore \: d \: = t_{2} - t_{1} = 6 - 3 = 3$

$\sf \therefore \: d = 9 - 6 = 3$

$\rightarrow \: \sf \pink {a = 3 \: and \: d = 3}$

Answer 2

Answer:

T1=3, T2=6, T3=9, T4=12,

T2-T1=6-3=3, T3-T2=9-6=3: :A=3,

D=3.
