$\huge \mathscr{\orange {\underline{\pink{\underline {Answer:-}}}}}$

The given sequence is tn = 7n+4.

The first term t1 can be determined by substituting n = 1 in the sequence tn = 7n+4 as follows:

t1=(7×1)+4 = 7 + 4 = 11

The second term t2 can be determined by substituting n = 2 in the sequence tn = 7n+4 as follows:

t2 = (7×2)+4 = 18

The third term t3 can be determined by substituting n = 3 in the sequence tn = 7n+4 as follows:

t3 = (7×3)+4 = 25

Hence, the sequence is 11,18,25,........
