Question

2, 7, 28, 63, 126...... Whats next term??

Answer 1

Hey there !!

A.P. 2, 7, 28, 63, 126, .....

a = 2

d = 7 – 2 = 5

or

d = 28 – 7 = 21

or

d = 63 – 28 = 35

Therefore, common difference is not same in the above case so, it's not an A.P.

Answer 2

This is not a real sequence... so it cannot have a next term.
