Question

Find the number of terms in the AP;2,5,6,.....50

Answer 1

Answer:

2,5,8,11..........50th terms common diff=3, 50th term=179

3,5,7,9,11...........50th terms cd=2,50th term=101

common terms are like 5,11,17.....101

LCM of both series=2&3=6

since in common terms the numbers are 5,11,17........101

a=5,d=6,t=101 we have to find n

t=a+(n-1)d

101=5+(n-1)6 =>n=17

Answer 2

Step-by-step explanation:

50= 2+3(n-1)

51= 3n

n=17

hope it helps you ❤
