2.8, 3.4, 4.0, 4.6, . . . Write an equation for the nth term of the arithmetic sequence. Then find a50.

vova2212 [387]

Answer:

a_n = 2.2 + 0.6 n

a_50 = 32.2

Step-by-step explanation:

What's the common difference of this series?

$a_1 = 2.8$

$a_2 = 3.4$

Common difference = $a_2 - a_1 = 3.4 - 2.8 = 0.6$ .

Expression for the nth term:

$a_n = a_1 + (n - 1) \cdot\text{Common Difference} \\\phantom{a_n } = 2.8 + 0.6 \; (n-1) \\\phantom{a_n} = 2.8 + 0.6 \; n - 0.6\\\phantom{a_n} = 2.2 + 0.6\; n$

n = 50 for the fiftieth term. Therefore

$a_{50} = 2.2 + 0.6 \times 50 = 32.2$ .

Which calculation will give the total surface area of the solid figure. look in picture

AURORKA [14]

Answer:

The Correct option is Last one

Therefore Total Surface area is

$\textrm{Total Surface Area Of Solid Figure}= 6\times 3\times 3\ square\ inches$

Step-by-step explanation:

The Figure shown is of Side 3 inches by 3 inches Square Shape.

So, Area Of Square surface is given by

$\textrm{Area Of Square surface}= side\times side$

So Each Square surface area is 3 × 3

In all we have 6 square

Therefore Total Surface area is

$\textrm{Total Surface Area Of Solid Figure}= 6\times 3\times 3\ square\ inches$
