Question

Find the number of terms in each of the following
2+ 4 + 6 + 8 + ... = 10100​

Answer 1

Step-by-step explanation:

Here a=2,d=2,tn=10100

By formula

tn=a+(n-1)d

10100=2(n-1)2

10100-2 =2n-2

10098=2n-2

10098+2=2n

10100=2n

n=10100/2

n=5050

Hence,the number of terms in each of the following is 5050

Answer 2

2+4+6+8 = 20

10100 /20 = 5050

This is the most simplest way I could put forward this answer .
