The 2nd, 6th, 8th terms of an A.P. form a G.P. , find the common ratio and the general term of the G.P.​
melisa1 [442]

The terms of an arithmetic progression, can form consecutive terms of a geometric progression.

  • The common ratio is: \mathbf{r = \frac{a + 5d}{a + d}}
  • The general term of the GP is: \mathbf{a_n = (a + d) \times (\frac{a + 5d}{a + d})^{n-1}}

The nth term of an AP is:

\mathbf{T_n = a + (n - 1)d}

So, the <em>2nd, 6th and 8th terms </em>of the AP are:

\mathbf{T_2 = a + d}

\mathbf{T_6 = a + 5d}

\mathbf{T_8 = a + 7d}

The <em>first, second and third terms </em>of the GP would be:

\mathbf{a_1 = a + d}

\mathbf{a_2 = a + 5d}

\mathbf{a_3 = a + 7d}

The common ratio (r) is calculated as:

\mathbf{r = \frac{a_2}{a_1}}

This gives

\mathbf{r = \frac{a + 5d}{a + d}}

The nth term of a GP is calculated using:

\mathbf{a_n = a_1r^{n-1}}

So, we have:

\mathbf{a_n = (a + d) \times (\frac{a + 5d}{a + d})^{n-1}}

levacccp [35]
Me :           4 x + 8 y   =  64
My friend:  8 x + 16 y = 128
A ) 4 * 4 + 8 y = 64
     16 + 8 y = 64
     8 y = 64 - 16
     8 y = 48
     y = 48 : 8
     y = 6 ( me and my friend work 6 hours at the second job )
B )  The number of hours we each work at the first job are also the same.

A jar contains 770 beans. Of them, 350 are mung beans and the rest are kidney beans. What is the ratio of mung beans to all the
MatroZZZ [7]

Answer:

5 MB : 16 B

Step-by-step explanation:

First, find the GCF of 770 and 350. ( 70 )

Next, divide both numbers by 70

770 / 70  = 11 Kidney beans

350 / 70 = 5 Mung beans

It says ratio of mung beans to <u>all</u> beans.

11 KB + 5 MB = 16 B

5 Mung beans to 16 Beans
