$t(n) = 2 {n}^{2} + 2n$

_________________________________

$t(1) = 2 ({1})^{2} + 2(1)$

$t(1) = 2 \times 1 + 2 \times 1$

t(1) = 2 + 2 = 4

##############################

$t(2) = 2 ({2})^{2} + 2(2)$

$t(2) = 2 \times 4 + 2 \times 2$

t(2) = 8 + 4 = 12

##############################

$t(3) = 2 ({3})^{2} + 2(3)$

$t(3) = 2 \times 9 + 2 \times 3$

t(3) = 18 + 6 = 24

##############################

$t(4) = 2 ({4})^{2} + 2(4)$

$t(4) = 2 \times 16 + 2 \times 4$

t(4) = 32 + 8 = 40

##############################

$t(5) = 2 ({5})^{2} + 2(5)$

$t(5) = 2 \times 25 + 2 \times 5$

t(5) = 50 + 10

t(5) = 60
