i need help figuring out this question! :)
write a equation for this sequence. then find the 100th term.
term number 1 2 3 4
term 6 10 14 18
Take a guess that the answer is a line.
Use any to points where the term number is x and the term value is y. Sove for the slope and intercept.
Terms 2 and 4 would give:
m * 2 + b = 10
m * 4 + b = 18
m = (18 - 10) / (4 - 2) = 8 / 2 = 4
If m = 4, what is b? (just substitute)
okay rebekka i don't get this question it says how many days will it take you to spend $i 000 000,if each day you spend each amount?
$ioo oo $io ooo $1000 $100 $10
The 100th term will be:
100 * m + b
m = 4 and b = ?
The 100th term is 402
Find the 35th term of the sequence in which a1 = 7 and the common difference is 7.
