4/2 = 2

97 + 2 = 99

A sequence starts 1,5,9,13,17<br> What’s the formula for the nth term of this sequence??

worty [1.4K]

This is an arithmetic sequence, since it's pattern is +4.

n1 = 1

d = 4

n = 1 + (n-1)(4) <-------------- This is the formula for the nth term of the sequence.

Determine the sum of the arithmetic series: 5+18 +31 +44 + ... 161.

Finger [1]

Answer:

1079

Step-by-step explanation:

Hello,

18-5 = 13

31-18=13

44-31=13

161=5+13*12

So we need to compute

$\displaystyle \sum_{k=0}^{k=12} \ {(5+13k)}\\\\=\sum_{k=0}^{k=12} \ {(5)} + 13\sum_{k=1}^{k=12} \ {(k)}\\\\=13*5+13*\dfrac{12*13}{2}\\\\=65+13*13*6\\\\=65+1014\\\\=1079$

Thanks

kkurt [141]

Step-by-step explanation:

here's the solution: -

if the given triangles are similar, then their corresponding sides will be in proportion, so

=》

$\frac{x}{14} = \frac{x + 11}{21}$

( by cross multiplication )

=》

$21x = 14x + 154$

=》

$21x - 14x = 154$

=》

$7x = 154$

=》

$x = \frac{154}{7}$

=》

$x = 22$
