The first term of an arithmetic sequence is -22. The common difference of the sequence is 5.

What is the sum of the first 30 terms of the sequence?

the sum of the first 30 terms of the sequence is 1515

Step-by-step explanation:

The formula for determining the sum of n terms of an arithmetic sequence is expressed as

Sn = n/2[2a + (n - 1)d]

Where

n represents the number of terms in the arithmetic sequence.

d represents the common difference of the terms in the arithmetic sequence.

a represents the first term of the arithmetic sequence.

From the information given,

n = 30

a = - 22

d = 5

Therefore, the sum of the first 30 terms, S30 would be

S30 = 30/2[2 × - 22 + (30 - 1)5]

S30 = 15[- 44 + 145)

S30 = 15 × 101 = 1515

its ok i have one too and i also have big lips
