What is the common difference in the following arithmetic sequence? n an 1 –12 2 –1 3 10 4 21 –11 –1 1 11

Option (d) is correct.

The common difference in  the following arithmetic sequence is 11.

Step-by-step explanation:

 Given sequence,

  n            

  1              -12

  2              -1

  3              10

  4              21

We have to find the common difference of the given arithmetic  sequence,

Common difference of an arithmetic sequence can be find by subtracting the term from the term preceding it.

Finding difference between the terms,

Thus, the common difference in  the following arithmetic sequence is 11.

Hence, option (d) is correct.

11 is the answer.

Step-by-step explanation:

We have given a arithmetic sequence.

12,-1,10,21

We have given 4 terms of arithmetic sequence.

a₁=-12 , a₂ = -1 , a₃ = 10 and a₄ = 21

We have to find common difference in the sequence.

Common difference is defined as the difference between consecutive terms.

d = a₂-a₁

Putting values in above formula, we have

d = -1-(-12)

d = -1+12

d = 11

Hence, common difference in the given sequence is 11.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

1st part is 64,000,000

2nd part 500,000
