7,13,19.....205
an =.a+ (n-1)d
hence a =7
d = 13-7 = 6
an = 205
an = a+(n-1)d
205 =7+(n-1)6
205 -7 =(n-1)6
198 = (n - 1) 6
198÷6 = n-1
33 = n-1
n = 33+ 1
n = 34
an =.a+ (n-1)d
hence a =7
d = 13-7 = 6
an = 205
an = a+(n-1)d
205 =7+(n-1)6
205 -7 =(n-1)6
198 = (n - 1) 6
198÷6 = n-1
33 = n-1
n = 33+ 1
n = 34
