Question

if a=10 d=10 tn=100 find n=?​

Answer 1

Answer:

tn=a+(n-1)d

100=10+(n-1)10

100=10+10n-10

100=10n

n=100/10=10

Step-by-step explanation:

n=10

Answer 2

Answer:

We all know the formula of finding the nth term:

Tn = a + (n-1)d

We know all the values ; Tn=100,a=10,d=10

So just put the values in the above formula

100 = 10+(n-1)10

100 = 10 + 10n-10

100 = 10n

n = 100/10

n = 10
