In an arithmetic sequence, the sum of the first n terms is s_n=n^2. find a_8

Julli [10]

Answer:

$a_{8} = 15$

Step-by-step explanation:

$a_{1} + a_{2} + ..... + a_{7} + a_{8} = 8^{2} = 64$

$-a_{1} - a_{2} ..... - a_{7} = - 7^{2} = -49$ Now add the two equations

$a_{8} = 64 - 49 = 15$

$a_{8} = 15$

How do I do this problem?

Aleks04 [339]

To solve the problem, we can use the angle sum of triangle,where the addition of all triangles would be equal to 180°.

In this case, 90° is already given, hence we can use the rest angles with unknown to set up equaiton:

90° + 2x + 3x = 180°

2x + 3x = 180°- 90°

5x = 90°

x = 90°/5

x = 18°

Therefore, x= 18°.

Hope it helps!
