D.0.95

Answer 1

$\huge\Black {Answer}$

C. 1

The pattern is + 0.05, + 0.10, + 0.15,.....
So, missing term = 0.8 + 0.20 = 1.

Answer 2

Answer:

$Option \:\pink { (C)} \:is \: correct$

Step-by-step explanation:

$Given \: sequence \:0.5,0.55,0.65,0.8,\cdot\cdot\cdot\\we \:can\: observe \:the \: pattern$

$First \: term (a_{1}) = 0.5$

$Second \:term(a_{2})\\= a_{1} + \pink {0.05}\\ = 0.5 + \pink {0.05} \\= 0.55$

$Third \:term (a_{3})\\= a_{2} + 2\times 0.05\\= 0.55 + 0.1 \\= 0.65$

$Fourth \:term (a_{4}) \\= a_{3} + 3\times 0.05 \\=0.65 + 0.15\\ = 0.8$

$Fifth \:term (a_{5})\\ = a_{4} + 4 \times 0.05 \\= 0.8 + 0.2 \\= 1$

Therefore.,

$Option \:\pink {(C)} \:is \: correct$
