Question

considor arithematic sequence 2,11,20......(a)is 101 is term this sequence

​

Answer 1

ans:Yes

explanation-(let it is term in sequence let's see it satisfies n value or not)

tn=a+(n-1)9

101=2+(n-1)9

101=2+9n-9

101=-7+9n

101+7=9n

108=9n

108/9=n

n=12 we found n value hence it is term in the sequence
