Answer 1

Hi Mate!!!

1) Common difference (d)= Tn - Tn-1

=>. d = 7 - 4n - ( 7 - 4(n-1))

=>. d = -4

2)

Next term will be the fourth term I,e

Next term = a + 3d

Where a is ist term and d is common difference

a = √(8). d = √ ( 18 ) - √ ( 8 )

d = √2

So, next term = √( 8 ) + 3 ( √ ( 2 )

=>. 5 √2

Have a nice day
