Answer 2

★ Given that,

• a = 7
• d = - 2

We know that,

Form of AP : a, a + d, a + 2d, a + 3d...

• Substitute the values.

$\rm\:\implies 7, 7 + (-2), 7 + 2(-2), 7 + 3(-2)...$

$\rm\:\implies 7, 7 - 2, 7 + (-4), 7 + (-6)...$

$\rm\:\implies 7, 7 - 2, 7 - 4, 7 - 6...$

$\rm\:\implies 7, 5, 3, 1.....$

$\underline{\boxed{\bf{\purple{ \therefore AP = 7,5,3,1.....}}}}\:\orange{\bigstar}$
