Answer:

Question

✳️Find first term of the sequence tn=2n+18

Solution ⬇️

✍️tn=2n+18

✍️a+(n-1)d=2n-5+24

✍️a+(n-1)d=24+5(n-1)

✳️ Comparing on both the sides

✍️a=24 : d=5

✍️T1(a)=24

✍️by using Formula

✍️t2=t1+d

✍️t2=24+5=29

✍️t3=t2+d

✍️t3=29+5=34

✳️ therefore the 1st three terms are 24, 29 and 34
