Answer:
c. 2+4(n-1)
b. 4+3(n-1)
Step-by-step explanation:
Look at the pattern: it starts at 2, and each term afterwards goes up by 4 each time. 2+4 = 6+4 = 10... et cetera.
2+4(n-1) is the equation.
Test this out with the fifth term.
t₅ = 2 + 4(n-1) = 2 + 4*4 = 2+16 = 18
Test it out with the first term, too.
t₁ = 2 + 4(n-1) = 2 + 4(0) = 2
If you follow the same pattern with part b, you find that the equation is
4+3(n-1)
Test it in the same manner.
