Question

a/b,ab,a-b,a+b are four terms of AP if the AP have 5 terms find the fith term...​

Answer 1

Answer:

-117/40

Step-by-step explanation:

find th common difference by substracting

two consecutive terms...

i am taking last two terms...

a+b -(a-b) = 2b

we got d = 2b

therefore,

a-b - (ab) = 2b

solving this u will get a relation between a and b

b = a/(a+3)

now substitute everything in terms of a in the equation

ab-a/b = 2b and solve for a....

a = -9/8

b = -3/5

now you can get the fifth term...

Answer 2

HELLO GUYS

Find the common difference by

substracting

two consecutive terms...

i am taking last two terms...

a+b -(a-b) = 2b

we got d = 2b

therefore,

a-b - (ab) = 2b

solving this u will get a relation between

a and b

b = a/(a+3)

now substitute everything in terms of a in

the equation

ab-a/b =2b and solve for a....

a=-9/8

b= -3/5

now you can get the fifth term...
