Question

Find, if 50 is a term of AP 4, 7, 10, 13............or not. if yes find which term it is​

Answer 1

Answer:

Step-by-step explanation:

a =4

d = 7-4 = 3

an = 50

n = ?

an = a + (n-1)d

50 = 4 + (n-1)3

3n -3 + 4 = 50

3n + 1 = 50

3n = 49

n =49/3 which is not a whole number. Hence 50 is not a term of this AP
