Sagot :

Answer:

The sum of the arithmetic terms is 110.

S10 = 110

Formula

[tex] = \frac{n}{2} (2a1 + (n - 1)d)[/tex]

where,

S is the sum or series

n is the number of terms

a1 is the first term

an is the nth term and,

d is the common difference equals to 2 from 4-2.

Substitute:

[tex] = \frac{10}{2} \: (2(2) + (10 - 1)2)[/tex]

[tex] = 5 \: (4+ (9)2)[/tex]

[tex] = 5 \: (4+ 18)[/tex]

[tex] = 5 \: \times 22[/tex]

[tex] = 110[/tex]
