The nth term of a sequence is 10n – 8 .Find the 20th term and 50th term.

192

492

Step-by-step explanation:

aₙ = 10n - 8a₂₀ = 10*20 - 8 = 200 - 8 = 192a₅₀ = 10*50 - 8 = 500 - 8 = 492

Subtracting is the opposite of adding

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
