Question

What is the common difference between successive terms in sequence 9 2.5 -4 -10.5 -17

Answer 1

Answer:

Common difference(d) states that the difference between the two consecutive term of the arithmetic sequence

Given the sequence:

9, 2.5, -4, -10.5, -17

This is the arithmetic sequence with common difference

i.e, d = -6.5

Since,

2.5 - 9 = -6.5

-4-2.5 = -6.5

-10.5 -(-4) = -10.5 + 4 = -6.5

-17 + 10.5 = -6.5

Therefore, the  common difference between successive terms in the given sequence is, -6.5

Answer 2

Common difference, d = 2.5 - 9 = -4 - 2.5 = -6.5

Common difference = -6.5
