The sequence:
-18 , -22.5 , -27 , -31.5 , -36
Common difference:
(-18 - -22.5) = (-22.5 - -27) = (-27 - -31.5) = (-31.5 - -36) = 4.5 ( When two minuses come together, they make a plus. So difference is certainly the positive next number - positive previous number to give 4.5)
Common difference = 4.5
Type of the sequence: Arithmetic sequence.
The equivalent value of the equation is A = 160 = 20 x 8
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be p
Let the second number be q
Now , A = pq
when the value of p = 20
And , when the value of q = 8
On simplifying the equation , we get
160 = 20 x 8
So , the left hand side of the equation is equated to the right hand side by the value of ( 20 x 8 )
A = 20 x 8
A = 160
Therefore , the value of A = 160 = 20 x 8
Hence , the expression is A = 160 = 20 x 8
