Question

The common difference of the progression 11,7,3,.........is

Answer 1

HELLO THERE!

The rule to find common difference between numbers in a series is:

Subtract the first term from the second.

The given series is: 11, 7, 3.....

Common difference = 7 - 11 = -4

The difference will be the same when you subtract the second element from the third (3 - 7 = -4).

Hence, the four numbers are in Arithmetic Progression (AP).

THANKS!
