Question

find the number of terms in each of the ap is 7, 13, 19 dash dash dash, 205​

Answer 1

Step-by-step explanation:

given

a1=7

d=6

formula to find n th term in ap is

an = (a1 + (n – 1) d)

205=7+(n-1)6

205-7=(n-1)6

198=(n-1)6

198/6=n-1

n-1=33

n=33+1

n=34

therefore 205 is 34th term or number in the given ap sequence

so the total number of terms are 34 from 7 to 205
