Answer 1

The nth term is 35+ 7(n-1) or can be written 28 + 7n

Explanation:

This is an arithmetic sequence, where each term equals the previous term, with a constant value added.

T1 = 35

T2 = 42 = T1 + 7 = 35 + 7

T3 = 49 = T2+ 7 = 35 + 7 + 7 = 35 + 2x7

…

The nth term is equal to 35 + 7X(n-1)
