Answer 2

$\huge \mathfrak {Hey Friend!}$

$\huge \bold {SOLUTION ;}$

$<b ><i >$ Given, first term, a = - 15

Common difference, d = - 11 - (-15) = 4

So, a5 = a + 4d = - 15 + 4*4 = - 15 + 16 = 1

a6 = a + 5d = - 15 + 5*4 = - 15 +20 = 5

a7 = a + 6d = - 15 + 6*4 = - 15 + 24 = 9

Hence, the next three terms are 1, 5 and 9.

Hope you got it!
