$\huge\sf\mathbb\color{yellow} \underline{\colorbox{lightblue}{☠✨answer☠✨}}$

Step-by-step explanation:

a = 0.6, d = 1.7 - 0.6 = 1.1, n = 100

$∴ \: \: \: from, S_{n} = \frac{n}{2} [2a+(n-1)d],$

$\: \: \: \: \: S _{100} = \frac{100}{2} [2 \times 0.6 + (100 - 1) \times 1.1 ]$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: = 50(1.5 + 99 \times 1.1)$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: = 50 \times (1.2 + 108.9)$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: = 50 \times 110.1$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: = 5505 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: answer$
