Answer 1

$\huge\boxed{\texttt {\fcolorbox {red} {aqua} {SOLUTION ;}}}$

$<b ><i >$ 1. Given,
First term, a = 10
Common difference, d = 7 - 10 = - 3
N = 30

So, a30 = a + (n-1)d
= 10 + 29× (-3)
= 10 + (-87)
= 10 - 87
= - 77

So, option C) is correct.!

2. Given, a = - 3
d = - 1/2-(-3)= - 1/2+3 = 5/2
N = 11

So, a11 = a + 10d
= - 3 +10 × 5/2
= - 3 + 25
= 22

So, option B) is correct!
