in this ap a=203.....d=7.....tn= 294
tn=a+(n-1)d
294=203+(n-1)7
294=203+7n-7
294=196+7n
294-196=7n
98=7n
n=98/7
n=14
there are 14 numbers between 200 and 300

AP is 203,210,217...........................294
a = 203
d = 07
an = 294
an = a+(n-1)d
294 = 203+(n-1)7
294-203 =(n-1)7
91/7 = (n-1)
13+1 = n
14 = n
therefore, n = 14
a = 203
d = 07
an = 294
an = a+(n-1)d
294 = 203+(n-1)7
294-203 =(n-1)7
91/7 = (n-1)
13+1 = n
14 = n
therefore, n = 14
