Step-by-step explanation:
n ∈N means that n is an element of Natural numbers
Natural numbers are whole non-negative numbers
n ≥ 1, means that n = 1, 2, 3, 4, 5, 6,........
tn = 32 + 3n
the first term t1 = 32 + 3(1)
32 + 3 = 35
the second term t2 = 32 + 3(2)
32 + 6 = 38
the third term t3 = 32 + 3(3)
32 + 9 = 41
