Question

given the first term is 5, coman difference is 3 and Nth term is 50, find the number of terms​

Answer 1

Answer:

first term (a) = 5

common difference (d) = 3

nth term (an) = 50

by applying formula

an= a+ (n-1) d

50= 5 +( n-1) 3

50= 5+3n-3

50=2+3n

50-2= 3n

48/3= n

16 =n

number of terms are 16
