Question

Find the number of terms of the
following Arithmetic progressions
7,13,19.....205​

Answer 1

Step-by-step explanation:

first number (a) is 7

common difference (d) is 6

nth term is 205

and as we know...

nth term of an AP is = a+(n-1)d

so 205=7+(n-1)6

198=6(n-1)

n-1=33

n=34

so there are 34 terms in this AP
