a = 6
d = 4
an = 174
n = ?
an = {a+(n-1) xd}
=> {6+(n-1) x 4} = 174
=> (n-1) x4 = 174-6
=> n-1 = 168 /4
=> n = 42+1
=> n = 43
Therefore, there are 43 terms in the AP.

Hi,here ur answer
common different is 10-6=4
first term =6
last term =174
let "n" term be last term
we know that
a+(n-1)d=174
REPLACE the VALUE
6+(n-1)4=174
(n-1)4=174-6
(n-1)4=168
n-1=168/4
n-1=42
N=43
So,this is ur sweet answer.
