If the 2

nd term of geometric sequence is − and the 5

th term is . find the first

three terms of gometric sequence.

, - 3, 6.

Step-by-step explanation:

Let us assume that the geometric sequence is given by  

a, ar, ar², ar³, .........

where a is the first term and r is the common ratio.

Now, given that 2nd term of the G.P. is -3 i.e. ar = - 3 ........ (1)

And the 5th term of the G.P. is 24 i.e. .......... (2)

Now, dividing equation (2) by equation (1) we get,  

⇒

⇒ r = - 2

Therefore, from equation (1) we get, a( - 2) = - 3

⇒

Hence, the first three terms of the G.P. are  , - 3, 6. (Answer)

a

step-by-step explanation:

its wrong

question: match the eqaution with its graph -8x - 5y = 40

answer: 8 x 5 = 40

x= absiss

y= orderly

so you have a proportional graph
