Answer 1

$\huge\boxed{\red{\bold { Solution}}}$

n=5

a=5

d=6

$s(5) = \frac{n}{2} (2a + 4d) \\ s(5) = \frac{5}{2} (2 \times 5+ 4 \times 6) \\ s(5) = \frac{5}{2} \times 34 \\ s(5) = 105$

AP=5,11,17,23,29

Answer 2

Step-by-step explanation:

$good \: afternoon$

$here \: is \: your \: answer$

$s(5) = n \div 2 \: (2a + 4d)$

$s(5) = 5 \div 2 \: (2 \times 5 + 4 \times 6)$

$s(5) = 5 \div 2 \: (10 + 24)$

$s(5) = 5 \div 2 \times 34$

$s(5) = 105$

$a.p. \: 5 \: 11 \: 17 \: 23 \: 29$

$thanks$
