Find the 13th term in the following arithmetic sequence :
2, 5, 8, 11, ...
Hint: Write a formula to help you.
1st term +common difference(desired term - 1)

38

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 2 and d = 5 - 2 = 3 , thus

= 2 + (12 × 3) = 2 + 36 = 38

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

you,

mrb

hope this !

let me know
