Question

which term of the AP 3,8,13,18 ........ ........ is 78​

Answer 1

Answer:

a = 3 ( First Term )

d = 5 ( 8 - 3 = 5 , common difference)

and nth term = 78 (nth term is denoted by "an")

an = a + (n - 1) d

.78 = 3 + (n - 1) × 5

78 - 3 = ( n - 1) ×5

75/ 5= (n - 1)

15 = ( n - 1)

n = 16

Hence 16th term of the AP will be 78
