Question

find the missing terms of x and y of the arithmetic sequence 8, x, 16, y, 24...........​

Answer 1

x-8=16-x

2x=24

x=12.

y-16=24-y

2y=40

y=20

so required answer is 12,20

Answer 2

Answer:

X= 12, y=20

Step-by-step explanation:

Observe the series,

this is increasing series

Which means x<y

Now we need to check for the common difference

X-8 which will be equal to 16-x because the sequence will have the same common difference from starting to end

(Where Common difference is difference between any two consecutive numbers of sequence)

X-8=16-X

2X= 24

X=12

Similarly calculate for y

Y-16=24-Y

2Y=40

Y=20
